The scanner tries to start a scan, goes into scanner warming up, waits a while then errors with the message "scanner failure". This happens from the control panel or from the PC. The light comes on and it has no trouble moving. Is there a thermister adjustment some where? Does any one one know of a fix? Thanks in advance.

Hi Ric
The only thing you can try is make a copy using only your PSC . If the problem persists , it may be a problem with scanner lamp . Contact an Assistance Support.

hi. i have this same problem with my psc 750. its just started happening one day for no apparent reason. as Ric said it still goes through the warming up stage and moves around a bit but then just stops with the message: 'scanner failure. turn power off then on again.' also, now i am unable to print as well. when i go to print something i makes a couple sounds like its trying to feed the paper, and then it stops and i get the same 'scanner failure' message. i would very much like to know what is causing this and what the solution is but cant seem to find any answers.
Ric if you have had any luck with yours since your initial post please help!...thanks alot. |

Try a different wall outlet, the machine may not be getting enough power.
If issue still persists
either exchange it at the store if it is within exchange policy or call tech support and have unit serviced |

I have the same problem with "scanner failure" on the PSC 750. Scanner bulb lights up fine, but unit doesn't get past "warming up" stage. Problem began one month after the warrantee expired. Unit still prints ok. Can anyone out there estimate what the fix from HP tech support will cost? If over $100, might as well retire this as a "printer only" for my son and go buy some other psc unit. Other HP products have worked great, but scanner failure on this unit sounds like a headache for many users and HP alike. |

I too am having this problem with the same symptoms. Printer displays "warming" for 30-60 seconds, then "scanner failure. power off then back on again" This occurs when initiating a scan either from the PC or from the device panel, or when using the copier function. I would sincerely appreciate some sort of clue as to what the problem is. |

Remove power and leave out for 30 seconds. Hold cancel and left arrow and reinsert the power. Attempt to copy, if it still does not work you may need to have the unit serviced. Technical support can set-up an exchange if in/out of warranty, if out... it will be more that $100 for another unit. You can try to call some local providers for a quote on prices as they vary from ASP.
Cheers! |

I've got the identical problem with an R80xi. The printer functions correctly, but copying is an issue. This problem came and went for a short while and I used to fix it by replugging the ADF cord that's really too short and has no lock on it to keep it in place. That doesn't work anymore. I suspect it is in the lamp or the temperature sensor for the lamp. Any help on this would be greatly appreciated. Seems that this is a fairly common problem on the multifunction machines, especially those with a little mileage on them. |

I bought my psc750 3 weeks ago and had this problem from the day I installed it. I finally figured out that there was a conflict between my HP and my Iomega zip drive (HP and Iomega don't get along real well together...I've encountered this before). Once I unplugged my zip, the scanner worked fine...for about 2 weeks. I'm having the same problem again now and unplugging other devices doesn't seem to help. I'm still optimistic about finding a fix. Most of the reviews I've read about the 750 are MUCH better than those of the machine that replaced it. |

I also began having this problem almost immediately after my hp psc 750 went out of warranty. Tech-support was good enough to try to help me out and suggested that I plug the unit into the wall outlet rather than a power strip. I thought my problem was solved but it still persists. I'm sure that hp could at least id the problem so that we wouldn't have to be shooting in the dark on this.Les. |

There is some stuff that can be done for this, but if it doesn't work, you'll probably end up needing to contact technical support, and having them service the unit.
1) Make sure the unit is plugged into a wall and not into a surge protector.
2) If that doesn't work, try a reset. For the PSC750s, unplug it, ahold down Cancel and the Left Arrow buttons, and plug back in. The R80xi, if I recall correctly, does not have a reset.
3) If that doesn't work, you'll likely end up having to contact tech support. Unless the room is very cold. That can cause problems too. |

For the scannner failure error message, I would suggest you check the following steps.
The Scanner System Failure error occurs if the scanner bulb is not
being heated up to the correct temperature or there is some other
issue with the scanner hardware. Verify that the scanner bulb is lit.
Power cycle the all-in-one product and see if the error comes back.
Perform the steps given below to power cycle your all-in-one product.
1. Shut the computer system off, then disconnect the all-in-one
product from the power source. Leave the all-in-one product
disconnect from the power source for at least one full minute.
2. Reconnect the power, then restart the computer system.
If it does, take it off of any power strip and plug it directly into a
wall power outlet. The power strip may not be supplying enough power
to the product. Cold ambient room temperatures may also cause this
error. Try moving the unit to a warmer room and see if the error
reoccurs. The unit will need to be serviced if the bulb does not come
on.
Perform a semi-full reset by following the steps given below:
Caution: A semi-full reset will reset or clear the following
information:
* Return the user settings to the factory defaults
* Delete language and country settings on some models
* Fax logs
* Fax headers
* Fax speed dial information
*** HP PSC 700 series, HP Digital Copier 310 ***
Press and hold Cancel and the Left Arrow key while plugging in the
power cord.
If the issue still persists..I would suggest your remove and reinsert the cartridge. |

The problem you are experiencing is not limited to the PSC 750, it is also happening on my PSC 2210 and its only 3 months old and produced a total of 610 pages of text - and scanned about 10 pages in its life. Agree with other submitters - this is an identifiable problem with HP products, they are not up to merchantable quality, and should be returned to the vendor - which is what I will be doing. Before I do though, I will take the advice of others to try a separate wall plug for it - but come on HP, we live in a technological age and this is not something we should have to do. Imagine if we had to do that for every product we ever bought. You need to own the problem and fix it. |

I cannot see this being the problem as the scanner works when it is re-installed. If the glass was dirty and not connecting with the sensors then it would not scan at all. I find that when I open an excel spreadsheet, that is sure to lose the scanner. It is really a weird problem and one that has me baffled. |

Redram is the man. I am Ric the originator of this thread. After trying all the suggestions I was at the point of throwing it out and getting another all-in-one. I cleaned the mirrors and lens and away it goes.

This is a question for redram or Ric or anyone else who has successfully repaired their psc750. The part I am stuck at releasing the belt tensioner to get the belt off of the drive gears.
"You will need to release the belt tensioner located at the scanner head end of the belt. It's got a slot and another detent. Just pull it back and then lift slightly so that the pin aligns with the detent and it will hold in place with no tension on the belt. Sounds worse than it is. Then disengage the belt from the toothed drive gears at either end."
At the scanner head side of the belt I am only seeing the gears the power the belt. Is it on the scanner head itself? If so I still dont see anything matching that description, only the place where the belt is connected to it but I cant do anything with that.
Im just nervous about breaking anything so rather than messing around Ill ask this potentially dumb question. |

Not the scanner head "side" of the belt, but you are at the correct end of the belt. The other side of the belt should have a small plastic clip with a spring attached to it. Releasing the spring will make it a little easier to lift and pull back the tensioner.
After you clean the mirrors, the unit may go through a few more "scanner failure" errors before re-adjusting itself (mine did), and after 26,000 pages it works perfect again, although I did totally disassemble unit, and cleaned out that hidden inkwell.
Good luck

Hello,
I've got the exact same problem with my rarely used officejet G85. Just after the warrenty ran out.
I already cleaned all the mirrors but unfortunately the failure message didn't disappear.
It's really a bad that this seems to be a frequent problem through all of HP's all-in-one devices and there is no official solution for it.

Positive report: I finally remembered to get the Torx (R) screwdriver set from the hardware store today (why did HP use this type of screw - to make it more difficult to try home remedies?). I've cleaned the mirrors, and - after several months of being on the disabled list - my PSC 750 is scanning again. Note that it wasn't occasionally failing scan test or even occasionally working; it was a goner....on dozens of attempts prior to the cleaning.
On a side note, the page referred to by redram's link above no longer contains anything (it's blank), but knowing that the mirrors are a common culprit was enough info for me. A few places in the disassembly are dainty, but it's not difficult. Good luck all. |

I have the same problem with my PSC750.
However, I also get the problem of the scanner head moving across a little every time I power on and off the unit.
It eventually goes all the way across and grates as it can go no further!
I have to open up the unit and manually push the scan head back to the proper park position.
Any help anyone? |

Hi, I HAD a problem with my HP PSC 950. Problem was the scanner error with the scanner head moving a little to the left when disconnecting/connecting the power. I tryed Redrams tips but it didn´t do the job. However the mirrors needed to be cleaned anyway. Checked the power from the PSU (Power Supply Unit) and it was OK @ 18V. I think the problem in my case was the scanner head was out of sync. Lost it´s home position at the far right side of the scanner/printer where it calibrates using a thin white strip at the underside of the lit. In desperation I tryed pressing different keys while plugging in the power as suggested for reseting. Suddenly the scanner head started to move to the right in small steps. It came to rest just under the calibration strip at the right side and NOW IT WORKS! The scanner head has finaly found home ;-)
Problem is I´m not sure what button combo I was pressing but I think it was * and # or try cancel and 6, just try different combinations if that doesn´t work. However don´t blame me if a button combination does harm to your printer/scanner.
What caused the error was probably some powerfailiure incidents during a stormy winter weather here in Sweden a couple of months ago. The power went on and off several times in a short period of time. Problem occured after that.
The psc950 is very nice (when it works) but I will try another brand next time.
I hope this solves a |

I fixed the problem with my HP 750. The symptoms were the same as described in these previous posts. I did 2 simple things. I don't know which one was the problem. I reset the printer using the menu, maintenance on the printer. Then I looked in the control panel (printers and faxes), right clicked the printer and chose properties. Under 'advanced' I noticed the driver was set to 700 series. I chose 750 instead. I tried my scanner and it worked. I had the sasser virus recently and I restored my computer. That's all I know. Unrelated topic. I also discovered my XP has a built in fax that does not need a fax modem, just a telephone connection to the computer. |

Well, it turns out I was wrong about the button combo trick. Now I think the fix was to let the machine rest without any electricity connected for about 24 hours. Someone has suggested this before me. When connected to the power again it calibrated the head position and works like new! |

It's definitely a resource problem I would say and usb related. When I do lots of scanning I unplug my other usb items eg modem, camera, webcamera. If I print large spreadsheats, I am sure to lose scanner function if I try to scan before rebooting. Better not to use up lots of memory before trying to scan. Hope this makes sense to you all. :O)) |

PSC 950 too. We have 4 of them here and every last one of them gives "scanner failure" errors. The first one started malfuntioning last August and we (wrongly) attributed it to Blaster or something similar and retired it to Fax receipt only duty. The second one went out when we converted to Windows XP. New drivers (a 62 megabyte! download) were installed and it sometimes worked. The others have also started doing it. We got the CD and no change. Sometimes when a text document is printed first the scanner will work fine for three or four copies or faxes. Then scanner failure. We have experienced way, way too much productivity loss battling "scanner failure" when trying to fax something to a client or make a copy of a document. |

My psc 750 had back the same problem again!
"The scanner tries to start a scan, goes into scanner warming up, waits a while then errors with the message SCANNER FAILURE."
Its has been replace within the waranty period and used it about 2 months but it was run out of warranty on date of purchase.
I know that HP had a best quality in product but why in this model............
Do HP company will replace my unit with the same or another model?
Do HP certified personnel can read this?
Do HP retail outlet in the Philippine can decide what to do?
Thanks if this was acknowledge. |

Normally ( here in Europe ) you get another 3 months warranty period. If these 3 months are in your normal warranty of 1 year, the end date just counts. When you get an unit exchange 1 day before the end of your warranty you'll have an extra 3 months warranty on the exchanged unit. You better can contact HP and see what they tell you, hope I informed you a bit

Yes, absolutely. The mirror and glass cleaning worked and continues to work for me. I've not had to do anything further to the machine since I did that.
I cannot, however, guarantee that this is the cause of your specific problem. It would be most helpful if you could post as much information about the problem you are having, when it occurs, what you've tried and so on.

I have a PSC750 which is out of warranty.
I first experienced the same problem of long periods of "warming up" messages and subsequent "scanner failure" messages.
I then used redram's instructions (sincere thanks Redram) to open up and clean my all-in-one and indeed found the mirrors & eye to be dirty. However, after reassembly the scan head which used to park on the right instead moves slightly to the left every time I power the printer on. When it reaches the far left, I hear the motor grate.
I have tried powering off and disconnecting from the mains for 24 hrs. I have tried a partial and full reset by pressing the cancel+left button/Enter button to no avail.
Even when I try to use the all-in-one as a copier (disconnected from my PC) is doesn't work - this leads me to believe that it is nothing to do with BIOS settings or printer drivers.
Can anyone help? I'm really desperate for any other suggestions (short of scrapping it!)... |

Hi All,
I, too, was experiencing the same problem with the PSC 750. If you are using Win XP, I think I may be able to help with a "work around fix." If your machine will print but not scan, try the following:
Right click on the desktop HP director.
Open Properties
Click Compatibility Tab
Check "Run this program in capabality mode for: Use Windows 2000 mode
See if this will fix the problem. There seems to be a glitch with one of XP's files called usbscan.
Hope this works.

To clean the mirrors and the bulb helps to avoid scanner failure.
How to clean without removing the bulb:
Take off the hood.
At the back side, on top behind the window, are two round holes. With a smal screwdriver you can take out the two screws.
Lift the back side of the window and at the same time click the front loose (first left then right).
The window can fully be taken off by disconecting the wire (there is a plug at the rear side of the window on the right side).
On top of the bulb and mirrors there is a black cap, you can remove it by putting a smal screwdriver in the two square holes
(one at a time) and pull the scewdriver to the right, the cap clicks off.
Now you can see the mirrors and the back side of the bulb (at the back side there is a wire). Clean the mirrors and the front side of the bulb using a wet cloth ( with your small finger you can clean the front side of the bulb, that looks down).
You don't need to remove the bulb!
Kind regards, Bon Moorkamp |

We went through the same Scan Failure problems with our HP D145 All-In-One and the technical chat could not help. However, the HP support from India resolved the problem, as follows:
-Disconnect system from Power and disconnect the port connection
-Hold the "On" Button for 2 minutes
-Reconnect power only. Power up, open flatbed cover and press Copy
-If light comes on and moves, problem may be fixed
-If not, press 3 and # on the kepad and disconnect power while holding the keys. Then release the keys and reconnect power.
-Press Copy and see if the scan light is on & moves
- If light comes on and moves, problem may be fixed. Try copying a document.
-If not, Press 6 and # keys together and disconnect power while holding keys. Then release keys and reconnect power.
-Press Copy and see if the flatbed scan light is on & moves. If yes, try copying.
- You may have to reset the date, time and language using the Menu functions.
- You can next reconnect the port connection and print from your PC to ensure PC-printer interfacing is still okay.
The above worked for us.
Your system may require different key combinations for resetting the system. See you manual or check with HP. Good luck!

This problem with the HP is popular with many models. I have a psc 950 that has had the same problem. I cleaned the scanning head and mirrors according to the info in previous discussions, however it did not solve the problem. I read on and discovered the reply on leaving the black cover off of the scanning head. I gave it a try and what do you know it works. So far so good. Sometimes it pays to leave a few parts out, I guess. If you have no success give it a try. |

I have two PSC 750 devices. I purchased one, liked it, and then purchased a second for my parents about 4 months later. The first started to show the problem 4 months ago and the second has now started to do the same. Both are now out of warranty.
One is in a thermally stable environment.
I have tested and both are in electrically stable environments which are well within operating tolerances.
Both are in clean environments without smokers.
The first device has failed on and off for four months. We have seen no pattern to the failures. I am not confident the fixes above are true fixes but false positives. I see some people have had success and others have not.
I took the device apart and inspected the mirrors. All the optics appeared to be clean, specifically, I could find no causal effect. I did proceed to clean the mirrors.
I was part of the team who developed the first desktop CCD slide scanners in the early 90's. I have written the CCD alignment and calibration routines. The calibration target under the bezel appears to be clean, white and uniform. I am surprised to see the edge of the white plastic background plate on the cover has a yellowish strip at the start of the scan area. Is this strip used for calibration? Is this first centimeter white to start and exhibiting an aging effect?
Has anyone had the mirror cleaning work to then fail later giving us readers a false measure of success? I am concerned that these people have given up, tossed the scanner, and stopped following the thread. Any feedback would be greatly appreciated.
We are in a difficult position. HP has built the right solution and I am certain sold these in large quantities. Is the failure rate so low those of us don't matter? Having two devices from different manufacturing batches running in different operating environments both show the same failure could be a statistical aberration or a sign of a high failure rate?
While HP technical support is trying to be helpful it would serve them to understand the root cause and to publish it here with the credentials of an engineer from the development team. This would serve HP to have field information go back into the development cycle and it would give the readers of this thread definitive information and trust in your brand.
I would be happy to be available to answer questions with an HP engineer, engineer to engineer. I would also be happy to exchange my printer so it can be inspected. |

Hi CCD engineer.
As a quick bit of feedback, I performed the mirror cleaning shortly before I posted the results roughly a year and a half ago.
My R80 continues to function without this failure re-occurring to this day and from what I've seen has been effective for others as well, though I think we would all appreciate some feedback on the longevity of the suggested repair.
While there is some merit to your train of thought, please understand that the same symptom can be indicative of different failures.
The mirror, target and "eye" cleaning does work when the only problem is "dirty mirrors". It does not work when a piece of circuitry dies or some other failure exists.
I believe there are others in this and related threads that have had some of those experiences.
As to HP commenting on this issue, their corporate solution is "send it in for repair". My take is that they cannot provide an alternative simply because there would be an implied guarantee and they are not in a position to guarantee that one "fix" is a cure for all these ills.
That is where the forums come in to play.
So, while your desire to engage in a discussion with HP over this is admirable, I doubt that any firm resolution will be achieved - simply because it cannot be.
What do I mean by this? Well, let's say there was a particular capacitor on a particular board that continually and repeatedly failed. Then a product issue would exist. Whether HP took responsibility for that would be up to them, but I believe we all could agree that would be a definitive product issue.
With multiple failures and a similar symptom, why should there be any responsibility from the manufacturer beyond the warranty period?
In the cases cited here, the cause of the reported "scanner failure" message comes from different faults. How can we ask HP to take responsibility for all of those? That doesn't seem appropriate or fair.
No, I'm not taking sides in this matter. I do believe there may be some responsibility on HP's part, but their legal staff probably prohibits them from anything further than permitting us end users to utilize this forum to all of our benefit.
Just my thoughts on this matter.
Oh, and you did say you took the machines apart and cleaned the mirrors and targets, etc. But, you didn't report the results. Did it work?
Let us know. And, thanks. |

My issue occurred just over 2 months ago with my HP PSC 750, and the fix worked great. Nothing inside my scanner looked dirty either. In fact, everything looked spotless. But I knew nothing of these things so I continued to follow the forum-given advice (carefully). And I'm glad I did. HP sure wasn't giving me anything to go on. Oh, they tried to help, but unltimately it was suggested that I take it to a qualified repair center. No acknowledgement of a possible product-line issue.
To be honest though, I had a little scare about a month ago when I got a scanner failure message immediately following the warming up message. I power cycled the scanner and I was back in business - just an isolated incident apparently. Other than that, everything has been great. |

This is just an update. I guess I am one of the lucky ones. My unit is still working since the fix in September 2003. All I did was clean the mirrors very carfully, I used alcohol and a lint free cloth.Good luck. |

Thank you for your responses.
The mirror cleaning on my part did not fix the problem which is still intermittent.
I believe the point made about the likelihood of multiple ways to fail is cogent - thank you. Therefore, readers should know the cleaning is one possible fix to one possible problem.
I commend HP for offering this forum.
I do not believe HP sets a dangerous precedent by talking with their customers and working to have their products survive past the warranty period.
I realize communication with customers is labor intensive and expensive. I offered myself as a person with expertise who could convey information from the field efficiently. As an engineer I am always looking for great customers to engage; It benefits all involved.
Thinking about it more I realize HP does not need to talk with us. They get us to pay $100 for the repair, give us a new machine which may cost less then that to manufacture, and send a subset of the returns back to the factory to be inspected.
I may try the repair route. If so, I will let this forum know my experience. Having two failed printers the benefit may be greater than the costs of fees and time. |

I guess I've been fortunate that I've had my 750 for over 3 yrs & have done endless copying & scanning - & this Scanner Failure didn't begin till a few weeks ago.
I've been searching this site for help, did the plugging directly into wall outlet instead of power strip - have uninstalled & re-installed it several times . . & tonight finally tried a google search for help & found this forum.
Now I've located & copied Redman's instruction file & jht's added info & all the other tips for help - & I'm ready to give this cleaning the glass & mirrors a try as soon as I pick up the needed screwdriver tomorrow (hope I can find where they're sold)
I had flashed my BIOS a couple of yrs ago & will check to see whether I need to do so again.
Since I re-installed Win98SE a few weeks ago, I also wonder why my printer is installed to the USB port rather than to LPT 1 printer port - & whether that is the problem, or how its supposed to be . . after an attempt to scan fails, I receive a "missing parameter" message, but all troubleshooting I've tried comes back fine.
Thanks for your help as my search for the solution continues (I sound hopeful, but I really hate all the time for this ;))

I have found a solution to the HP PSC 950. This solution works for this unit as well as many others. The problem does not lie with a physical problem such as the scanner lamp, mirror, glass or anything like that. The problem has to do with the drivers. If you have downloaded drivers from HP and are using those with your unit, u must change some of the settings. I downloaded the generic ph psc 900 drivers for my psc 950 and was able to print but got the "warming up" and "scanner failure" messages. To resolve the problem, go to control panel, printers and faxes, right click on the printer and go to properties, go the advanced tab, 1/3 of the way down you will see a driver selection, select the exact model of your printer. The drivers that one can download from HP are generic for many models. The user must select the exact printer that they are using. there may be other solutions to this problem, but this worked for me. |

Thanks, I will try that for the PSC 950. I had given up on them and broken our OfficeJet fax machines out of storage to use as our faxes and copiers while still using the PSC as printers. We will see if it works. |

Removing the black plastic cover WORKS! Thanks to all who contributed to this fix; I am very grateful.
This is a pretty easy solution, and only took me about 20 minutes once I had the right tool. For less than $10, I bought an Allen-style wrench set with "Star Key" tips, something I had never heard of before. Size T-10 is the right size to loosen the screws holding the top on.
Once the screws are loose, the top sort of unsnaps in the front, if you use gentle pressure in the right places. Look at the underside of the top to see where to apply pressure. Once the top is loose, there's a small ribbon cable that connects the scanning unit to the control panel that needs to be disconnected. Just pull gently straight out on the end of the ribbon cable away from the top, and it pulls right out.
Then I used the tip of a small flat-head screwdriver to gently pry the black cover off, starting with the edge closest to the front of the unit. Again, be careful and go slow. Once it's off, reattach the ribbon cable and reassemble the unit. It is a pretty easy task, and my PSC was able to copy for the first time in ages once i fired it back up again. Thanks, all! |

I experienced a similar problem. With my HP PSC 750 (not xi).
My problem was this. Everything worked, printing, scanning, everything... EXCEPT, for when I press "START SCAN" button. I would always get the "SCAN ERROR" "Unable to connect to PC (or something similar to that"
So that was my only problem. Pressing that button never worked. I set up my "SCAN TO's" and everything. Nothing worked.
I came here for help, nothing helped.
I used a tip to RESET my printer. Which was to... Unplug power from printer, hold down RED CANCEL button and LEFT ARROW button. A Partial RESET didn't help.
I explored this tip. So I held CANCEL button, then used different combinations, with CANCEL being the main one. I found 2 combinations, that helped. It was to HOLD buttons CANCEL and ENTER to do a FULL RESET. And also, HOLDing CANCEL and BLACK COPY button, works as well, doing a FULL RESET.
On fixing this issue, I found out what was the issue, It was cuz the SCAN TO's are buggy or programed very badly. Everything worked fine, the whole sha-bang worked. Until I upgraded to a new pc, I then installed everything all over again. Then I wasn't able to use that darn START SCAN button anymore. When I go to check my SCAN TO's, the setttings were from the first computer it was used on. I couldn't change anything, well... I could add new things, and take new things away, but I couldn't do anything at all to the old ones. So that was the problem with my case.
Hope this helps any of you. If this was posted already, then I'm sorry. I only skimmed this topic. 8D. Goodluck. |

Sorry, I forgot to add, another step to the fix.
Here it is all over again, with all the steps.
1.Unplug power cable from printer.
2.Hold Cancel and Enter. OR you could Hold Cancel and Black Copy Button. Whichever is easier
3.Then plug back in the power cable, while still holding those 2 buttons.
4.It should turn on, lights blink, then it should say FULL RESET on the little screen thingy .
5.Let go of the buttons, and hopefully, it fixed your problem. |

I purchased this machine in 2002 and was problem free until about 9 months ago. Everytime I changed the ink cartridges the "press enter to align cartridge" came on , So of course I would press enter and it would print a report then say the same thing again. Yes I purchased a warranty it is up in july of this year thru Staples. So I call all the 800 and 888 numbers I can find and they gave me a reset code which works until i have to change the ink again.
Well now I'm experiencing all of the above complaints about the 950. I can get a refurbished unit with a 100 day warranty, then my already paid for warranty is fulfilled as far as they are concerned. If they are all junk what's the point in getting a put back together one. HP wants a credit card and $30.00 just to hear my problems. I used to be very proud of the things I could accomplish with this machine too bad the only thing i'm accomplishing now is complaining. What should I do? Should I take it apart to clean the lense and things, but still what about the align cartridge? HELP |

I have been batteling this problem with my PSC 750 for quite some time. I was ready to through it out the window. I finally got some time and I found this site and thanks to all the great information I got the problem fixed.
The only thing that worked was taking it apart and cleaning the mirrors (which looked clean to me) and leaving off the black panel.
I wasn't so sure if the big black panel was the one that everyone was talking about, but it was the only one I saw. I hope that it doesn't pose a safty risk of overheating or catching fire or something like that.
I was really nervous about taking on the feet but I took my time and I was careful and everything turned out great. also you can use a small flat head screw driver to get the torq screws off. I had a torq bit but it was too fat to get in there.
The one problem that I did have was after it was all done, I don't think I got the belt matched up just right because I got a little grinding from the printer. any suggestions? I don't want to teeth on the belt to get worn down.
Thanks again to everyone. |

Okay. PSC 950 I had tried the advanced printer option setting it for 950 instead of 900 series. That actually worked for five or six copies, then back to our old friend scanner failure. Although I gave up business wise on the HPs around here and replaced them with the new Brothers multi function machines, I still have the HPs. Tonight I grabbed one of the HPs and did what Paul Tyler said. I was dubious that I could get the cover off the mirror without breaking it, but sure enough with careful prying with a thin blade off it comes without snapping. Reattached the ribbon and turned it on. The PSC now copies (for the first time in many months for this one).
Now, someone want to explain to us why removing the plastic dust cover that had no observable mechanical or electrical role in copier operation makes a difference? Is this because of increased light reaching a receptor, or what? If the first, then what is happening? Is the bulb dimming? Does the plastic on the light receptor grow opaque as it ages? Is something else occuring? C'mon you watching HP gurus, give with the answer to why removing the cover works. |

kay, now that the HP has been replaced, I felt free to dink around with it.
I went out and got the Torx tool and the top came right off like they said above.
So did the black part.
I cleaned the mirrors as best as I could reach but they din't seem dirty anyways... then I put it all together.
It took about 12 tries, with unplugging, full resets, and some petting and stroking.
Alla sudden, it made a copy.
Now it seems to work ok.
Once in a while, it burps to itself when I'm not using it, then blinks red.
eh. I just press the red button and it turns green again.
However, I can't get a dialtone for the fax like that other guy a couple posts up.
sigh. |

Ric, I have been fighting with this problem for days. I have two PSC's, 2175 and 1310. both have same problem. Had a 750 and I thought it had finally died. Was a good machine and gave long service but it too had displayed unable to comunicate message. Being on my third PSC I now believe the 750 is still OK.
After trying unsuccessfully to get new 2175 working on a 800 celeron machine I became curious and installed it on my AMD2600 (HP also)and 2175 works just fine. I am now going to try same with 1310 and 750.
My conclusion is that you need the latest and greatest hardware to run HP software as it is a high memory hog.
Over time our machines become plugged up with software and eventually the HP scanners stop working as they req. lots of memory.
If you are able, try PSC on a different machine or, more drastically, reformat your present machine. make the PSC your first install after getting back up and running. |

I haven't noticed any type of temperature sensor that would monitor the temperature of the light bulb. I think that the wait time is programmed in.
I tried the cover removal fix that somebody else on this board suggested and my scanner now works fine. I think that the alignment of the imaging unit (camera) has changed and that now the optical imaging unit cover is blocking a critical part of the image that the camera sees, causing it to produce an error. HP, would possibly trimming the edge of the cover along the imaging window fix this problem and still provide protection to the optics from stray light and contamination?
As somebody mentioned earlier, this is a remedy for just one specific problem that has the same symptoms as other problems can cause. Try the different remedies to see which one may work for your particular machine. |

there were two problems reported in this chain. I experienced the second one - I changed the cartridge, and could not successfully align the cartridges. The HP website has a solution for this, and it worked.

Good luck to all - and yes, the printing software did not work well under windows 98 (as suggested by other writers in the chain). It seemed to me that the printer doesn't clean-up after itself, and I have to delete tasks still running from the previous printing. |

Hey people,
Go ahead & call HP at 1-800-474-6836. All these are harwdare Issues. They will give u exchange if u are in warranty. For OOW ppl I would suggest to go for an upgrade trade in, Hp buys back the unit good prices & adjusts the amount for an upgrade to a newer model & they dont even charge you shipping.
Thanx

I too had the same problem with this PSC 750. I tried everything, then found this post. I removed the black plastic cover and it has been scanning now for a full day. Before the problem was solid.
I found this PSC 750 leaking ink all over in the trash. Someone must have been having the same problem. I took all the covers off and then hosed it down with a high pressure water hose and then let it dry out overnight. After I found an 18VDC power pack that would work, the printer powered up and printed OK. It was just the scanner that was not working. Thanks to the forum for the fix. I wonder why HP Tech Support has never chimmed in with some support on this issue? |

I don't recall one.
However I remember thinking that it was very hard to get at the mirrors completely, and that long white thin tube is the bulb, and very fragile.
IMHO I wouldn't try to clean the mirrors unless I had to, and then I'd use alcohol/vinegar to prevent streaking. |

I think it might be the B&W calibrating strip under the glass is dirty.
I have a HP Color Copier 190 with the same scanner failure problem. I took out the two star screws in back underneath the overhang and then found two press to release tabs under the front part that elevates when you open the front to change the cartridge. I took off the glass and frame and cleaned the underside of the glass. It had some light soot like dust.
I made sure to clean the part of the glass that is over the light-tube when it is at rest. This part of the glass has a narrow black strip with a narrow white strip. I think this strip of black and white is used to calibrate the scanner. I wiped the light-tube with a Kleenex for good measure.
SO FAR SO GOOD!

Thank you and thanks to everyone else who forwarded me tips and encouragement....it worked!!! After well over one to two years of frustration. I took the printer apart, cleaned it (although it really was dirty), cleaned the glass (which was) and removed the black cover. I left the cover off. Plugged it all back in and low and behold, it scanned on the first try. I left it on for a full 10 to 15 minutes and the error message has not come on - truly amazing. You all saved me a great deal of money and frustration. I am truly appreciative of the helpful information. |

I read all thise 'fixes' with interest as I am a service provider and have tried to repair these as they come in. Some I have been able to clean the glass and mirrors and get them to work. The PSC950 I was working on today did not respond to the cleaning nor removing the black cover. (These scanner failures are a product of there not being enough light reflected back off the white calibration strip on the underside of the glass.) HP probably has some way to recalibrate these via a maintenance mode but so far I have not seen any messages about it. But today I decided that, I can't make it any worse. I examined the scanner florescent lamp and saw there is a white reflective plastic piece under/behind the lamp. It appeared to have black stripes on it and I figured that those may absorb some of the light. I carefully removed the lamp, removing a black screw and easing it out of the aluminum holder. It pushed the white plastic out sideways and then turned it over and inserted it upside down. It is difficult because it is bent in a curve and you need to work against the curve. With the help of a torx driver to kind of bend the strip around it and gradually work it back into the holder I was able to reassemble the whole thing and test it. IT WORKED! Now there is enough light to calibrate and not get a scanner error. It's not easy but give it a try if all else fails. |

I wish to thank you all for the great advice. You saved me and I owe you, particularly the person who started this thread.
When I first had the problem I tried many things including power disconnect, reboots, power cord detachment, multiple reinstalls, and a lot of nasty words. This seems to be a reaccuring problem for me. I love the printer, but finally ran out of tricky fixes and was ready to replace it,until a few minutes ago.
Alas, the cleaning of the glass and foam cover, removing and reinstalling the cartridges, unplugging and replugging have fixed the problem, abeit temporarily.
This is the 5th HP I have owned. And I have purchased many for use in business. The new HP's in the $150 class looks flimsy. I will keep the Lexmark as a backup as I have lost confidence in the 750 psc to be reliable.
Gratefully yours,

Wow I see there are a lot more responses since last time I've been here.
Anyways, I tried cleaning the mirrors long ago and it didnt work. Then I tried removing the black cover several months ago and that did not work either. However, I think the problem in my case might be I screwed up the belt that moves the whole thing. I lost one of the tensioner spring things and in order to keep it taut enough I just stuck a little rolled up piece of paper behind one side of the bar. But it still doesnt work...can anyone tell me how taut the belt itself should be when fully reassembled? |

Cleaning mirrors on my PSC750 did not help in my case but removing the black plastic piece allowed the unit to work for the first time in weeks. (Has been problematic for months and finally decided to stop working altogether.)
Wondering outloud if removing the black plastic piece is the best solution available to us (Although at this point I am just happy to see it working.! I also don't see any reduction in quality at least from the scans that I have done so far.)
Note: I bought two PSC750s at the same time and started using the other unit that had been in a box for ~2 years. I may know shortly if the problem is relate to power on time/useage or just the age of some component. (bulb / calibration strip)
Many thanks to the people that posted their experience and suggested fixes.
Clint
PS: If this is just some white calibration thresshold, I am surprised that HP has not published a firmware upgrade with a fix. |

it's a really simple question and obviously you guys have all removed the belt to fix the problem...so can anyone please just tell me how stiff the belt should be when put back on (on a scale of 1 to 10, 1 being pretty loose and 10 being virtually no leeway)? i really think this is my problem because the head moves a little bit when powered on, but then just freezes, and i am assuming it's because its having a problem due to being to loose or to tight, after losing the spring.... |

No need to remove the belt to remove the black cover and clean the mirrors. (The cover pops off from the top)

I just want to say thank you to all who suggested the cleaning of the mirrors and glass and thr removeal of the black piece, Voila!!! It has risen from the dead!!!
I was very close to giving up and buying a new printer. It now scans, copies and with no problems.
I thought I was going to have to throw away the old PSC 750.
As for all of you at HP, it really is sad that you could not provide a fix for this. Obviously I was not the only one who experienced this problem and who knows how many people just tossed there old PSC 750 and went out and bought your newest model, pretty sad way of increasing your sales!!! |

I don't believe this would pass the litmus test for unfair business practices unless you could prove that HP designed in a flaw / timeout that forced the product to stop functioning.
(It would be an interesting test to replace the lamp and see if the lamp is actually the "failing" component. My guess is that over time the lamp output diminishes and does not meet some thresh hold coded into the firmware.)
HP is not obligated to provide service / support forever on any of their products. However, it is bad that HP hasn't jumped in to fix the problem.
If HP fixed the problem (which I believe could be done through firmware or a lamp replacement) people would keep buying ink cartridges for their PSC750 which is great high-margin business for HP. If they toss the PSC750 they will either:
Buy another entry level HP multifunction printer - which is at best a break-even proposition for HP. (HP makes money on ink not entry level printers.)
Response from HP would seem appropriate...

I've also had that problem, but right when I started up the printer:
* Initializing
* Warming-up
* Scanner Error, turn of and on again.!!!
So I've searched for some information and tried everything. Until I saw the post about taking out the black cover.
You're right!
It was rubing against the glass and now it shows no problems... well not quite, I downgraded back to WIN2K and I'm missing drivers, but the copying is working just fine!
Thanks guys!

For those who prefer pictures for disassembling the printer, check this out:
http://www.sintelsystems.com/R60/index.html
Even though it's for the R60, I have a r80xi and the instuctions for taking it apart still applied. The one step it does not show is removing this "black piece." The black piece is a plastic cover that faces UP. Once you remove it, you should be able to see the picture in the link titled Top View. I assume that once this piece is removed, you're done and can reassemble the printer.
Unfortunately, taking off the black plastic piece did NOT work for me. I hope the pictures end up helping someone else.

I have the R80xi. After getting the "scanner failure" I followed the instructions posted to this forum. Cleaning the mirrors helped for a while, though removing covers didn't. I then noticed what appeared to be the white backing behind the bulb shrinking. With nothing else to lose, I removed the bulb and used White-Out to paint the black interior areas of the holder. I haven't seen the "scanner failure" message since. |

I don't have a picture but can offer the following tip.
To remove the black cover, you need to insert a small screwdriver through the rectangular cutouts on the baacl cover and pry gently (while lifting slightly) to release the latching tabs.
I hope this helps...

I have a PSC 750 that is exhibiting the Scanner failure problem. I have tried the fixes described in this thread (cleaning mirrors, removing the black cover, cycling power, partial resets, etc.). Unfortunately none of them have worked.
I noticed that when I turn the unit on, the scan unit moves approximately 1 inch to the left (facing the unit from the front), stops and turns on the bulb. If I cycle the power enough times, the scan unit moves all the way to the left end of its rail and remains "stuck" in that position. Subsequent power cycles cause a grinding noise as the units tries to move further left but is not able to.
It appears that my scan unit does not know its location. I also have a PSC 2210. In comparing its operation at power-up, I noticed that the scan unit remains on the right side under the calibration strip. Because my PSC 750 always moves to the left on power-up, it immediately moves out from under the calibration strip. Thus, I believe that the scanner failure is caused by a failure to properly calibrate.
Has anyone else seen this left movement behavior? Is it normal? If not, any ideas on how to fix it?
Thanks for your help |

My first msg is to align my cartridges. It prints the page and tells me to put it on the glass and press enter. Then it fails
wiht scanner failure.
A little supporting invitation - this scanned find until it was moved - twice. Turn it on and it grinds a couple seconds from the gears under the glass on the right. Then it waits and finally 'scanner failure.
Disassembled and the scanner moves freely.
Cleaned mirrors. Left of 'black plastic cover'.
Any more?

I must have been asleep typing that message. I will do it again.
My first message when I turn on my 750 is to print the align page. I do, then I am to put it on the glass and press enter. I do and it doesn't. I finally get 'scanner failure'.
I disassembled the unit and cleaned and left off the black plastic cover. No change.
A little supporting INFORMATION (not invitation!) - this unit scanned fine until it was moved - twice.
Sorry for the error-filled message I sent the first time.

HP PSC 750 - Scanner Error - I could print, but when trying to copy or scan, I received the scanner error. I read through the posts. I cleaned the mirrors and glass, but kept the black plastic piece - no go. I removed the black plastic piece and Voila - copies and scans. I don't know why this is, or what the engineers intended for the black plastic piece, but it's off and in the closet.
Removal instructions:
1) unplug everything and move the unit to where you can work on it.
2) Remove the paper, and remove the hinged lid (tilt the lid to the up position and lift directly up and off).
3) Remove the push button cover which lifts directly off - straight up.
4) At the top of the button control module is a recessed release clip. Use a flat blade screwdriver and push down on the clip. While pushing down, slide the control button assembly down. lift the outside edge up (there are straight clips on the inside edge). Lift up slowly as the connection cable needs to be unplugged. the cable itself unplugs. Just pull down evenly grasping the top blue laminated section. The blue goes to the outside (contacts go to contacts on the inside). Set the button control unit aside.
5) Using a #10 Torx screwdriver, loosen the two screws in the back corners of the glass cover assembly. Lift the glass assembly up (like changing an ink cartridge), and pull the front lip left and right forward - there are two clips at these locations. Pull forward and lift up. Remove the glass cover assembly off and set aside. Note, tip over and remove the scews (best to remove and put back in after the cover is back fully in place). In reassembly, be sure to feed the control button cable back through the hole, and that it goes back into place the way it came out (including folding back into the slot under the button control assmebly).
6) The black plastic cover has two metal clips visible. These are not the release clips (they hold a glass piece in place under the black plastic cover). The release clips are outboard of these metal clips and are two slots. Insert a small flat blade screw driver, and push the handle toward the center. While prying, lift the cover at that end up, pry the other end and lift the black plastic cover off.
7)While you're in there, you might as well clean the mirrors and glass. At the front of the lamp on the botton, the lamp wires lead to a white two piece plastic connector. Unplug the lamp wires. Where the lamp is, toward the front is a black philips screw in the clear plastic piece that holds the front end of the lamp. Remove this screw, and lift the clear plastic piece with the front end of the lamp up slightly, and then pull the full lamp assembly forward and out. This will open the space to the mirrors and glass. Use a Q-Tip and small pieces of paper towell and glass cleaner to clean the mirrors and glass strips. I tried to remove these to clean them, but the metal clips were too tight.. better to clean it all in place.
8) Clean the bottom of the glass top assembly.
9) Reverse the above to reassemble. Be sure to plug the lamp back in, and the button control assembly. Leave the black plastic cover off.
10) Place the glass top assembly back in place, and snap it down before dropping the screws in the back holes.
Don't know why, but you should be good to go. |

ANOTHER SOLUTION:
Hello
I found this thread when my PSC 750 packed up about 6 months ago - the same scanner failure message that's been described. I tried everything mentioned above but with no luck.
Today I finally fixed the thing! The band that the scanner slides along was stretched and a bit worn. I tried ordering this from HP months ago. My order was "awaiting stock" for a ridiculous time. My emails were ignored for months until I was eventually told I could not purchase this part (because I'm a private individual and not a business was the excuse given). I tried ordering elsewhere but was told that the part was no longer made.
This week I found on ebay a PSC 750 with a broken glass plate and other dings (obviously been dropped) but otherwise fully working. So I've just swapped the band and now my PSC 750 is working perfectly again (touch wood!).
Hope this helps someone! |

Hello again. I'm working this time on an Officejet 7110 that seems to have the same problem - Scanner failure, etc.....
The disassembly is a little different, but basically the same. You do need the torx wrench to undo about eight screws.
The black cover snaps off the same and so far seems to have fixed the problem. I will wait a day or two before I celebrate. |

Waiting a day or two to celebrate is wise. Mine's broken again!
It can do photocopies, but my scans are lacking any red (like when the prints run out of red ink). I'd hoped it was a settings problem but now the scanner failure message has started again. So it looks like replacing the belt wasn't a total solution for me after all.
But luckily I have a plan B. I'll put the belt back into PSC I got from ebay with the broken glass. Then I can just swap the top sections over. The only reason I've been so keen to repair rather than replace is that my glass is scratch-free (I put a sheet of clear plastic on it on day one).
If anyone needs any other parts from it, post here |

I have a very old OfficeJet G85 that has just started giving me this Scanner Failure. That said, I also have just started keeping the AC on with summer upon us. So, don't laugh, but I just took my girlfriends hair dryer and stood next to the printer with the hair dryer blowing at high temperature directly at the vent on the right side of the printer. Mind you, I did not hold the dryer close enough to melt the plastic. If you do that, well then, you deserve whatever happens. Anyway, after about 5 minutes of continuous heat I was able to get the printer to power on without giving me the Scanner Failure 30 seconds after power on.
Since my light was coming on, I figured this had to be the ambient temperature issue and I guess I was right. I hope this helps someone else out there that does not want to have to spend money on a new all-in-one. |

I've an old G85 which has been giving the scanner failure error for many months now so I have relegated it to being a printer.
After reading the note above I cleaned the mirrors and glass with no result.
then I cleaned the small plastic encoder wheel on the belt drive motor and BRILLIANT it scans perfectly now. it also prints perfectly. Stangely though it won't copy, just outputs a blank sheet!!! |

I have had this printer for over 4 years now and loved it. It produced really great photo image prints. It's made very well (solid) unlike alot of the newer ones on the market. About 4 months ago, I got the scanner failure error message and it would not copy. It was about the same time I changed from Photo Shop 5 to Photo Shop 7. Every time I tried to scan, it would say scanning to Photo Shop 5 (which had been removed) it would warm up but not scan and the error light would go on. After reading all the posts on sites about this machine and it's common scanning and copying problem I tried a few suggestions. I am happy to say I fixed the problem. As stated in some of the posts do not use the HP drivers - remove it from the computer - then shut down the computer - after it restarts it will say found new hardware (the windows driver for the printer) and install it. I have been able to scan from photo shop will no problems but have yet to try it from the control panel on the printer.The copier is also functioning correctly as well. I'm so glad it's working again I really did not want to part with this printer. Hope this helps someone out . PS I have Windows XP |

"Although this forum started with a PSC 750 scanner failure, folks with r80xi all in one devices reported similar failures. I also experienced the failure with my r80xi and did most of the things suggested in this forum. My resolution was achieved with the help of HP tech support as follows.
1. Will the scanner make an offline copy of a document?
2. If yes, is the parallel port configured properly?
It should be configured for Enhanced Capabilities Port (ECP) mode in the BIOS.
You can check its status in Device Manager where the configuration will be stated. Mine was not configured for ECP.
I made the changes to the BIOS as described here:
http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc=us&docname=bpu08011&printable=yes&encodeUrl=true&
and my scanner is now working most of the time. If I do get the error, I shut down the PC & scanner for a few minutes and then turn them back on. Then the scanner works." |

Good information here. I would like to add my findings to the discussion.
The key seems to be the EYE, not the mirrors. Only a few threads above mention the scanner eye, and no real information is provided about it.
I have two R40xi units. The R series has all the same problems as the PSC series. Every unit seems to have this problem. I finally decided to do something about it.
Most people discuss (1) cleaning the mirrors, and (2) leaving off the black covers. I did that. Only helped a LITTLE. The mirrors were very clean, so cleaning could not help much. The scanner would work when turned on, but the next day...after it would awake from its 'sleep' mode, the scanner would crash. Yes, it would reset with the first power-off-power-on cycle, so this was an improvement (previously, it would take several power cycles before it would work.). So, while this was an improvement, it was not acceptable, because power-cycling the R40 would cause print problems with XP, which would force me to reboot the PC also.
So I re-read many discussions about his topic online, and decided to find the 'eye' and clean that. It was D-I-R-T-Y. Very dirty. Dirty on BOTH R40's that I have. The eye was the ONLY thing that was dirty inside the scanner, and it certainly was dirty enough to cause significant problems.
The EYE is located as follows: see the scanner bulb, and look around the middle of the bulb. You should see a round eye, approx the size of a dime, mounted near there, facing towards the bulb and also towards the small mirror. It looks like a small camera lens. I cleaned the eye by dipping a Q-Tip into Windex, wiping it several times, then wiping it with the dry end of the q-tip.
For the first time in 2.5 years, the scanner did not crash after awaking from its overnight sleep state. Problem solved. Clean the eye. |

FYI - you need a "T10" Torx screwdriver to take remove the first set of screws on the outside. (I had to take my whole printer to the hardware store in order to find the right one.) Just removed the infamous black plastic cover over the lamp, etc. inside and seems to work. Hopefully, my $1.37 (USD) Torx screwdriver fixed the problem! |

FYI, on the last OfficeJet 7110 that I worked on with the same scanner failure, the problem came back after removing the black cover and cleaning the mirrors and sensor. I took a look at the light source and the two small flourescent tubes seemed to be a little dark at each end. I suspect that this maybe the problem with this 7110. I would recommend that everyone set the default sleep mode to a lower level than the default 12 hours. This may increase the life of the bulbs. Maybe someone from HP tech support could comment on this bulb issue. (Ha! that will be the day!) I am only guessing on this, so take it for what it is worth. Bruce |

Upon power up, all large buttons blink and display shows "Error:c00f0401. Turn power off and on." Done this, as well as fullreset
as suggested in above responses...no help.

This thread is only for the HP Model PSC 750, Scanner Failure.
The "Removing The Cover Fix" may or may not work on other models. Probably not.
If you are having trouble with a different model other than the PCS 750, you should search for a thread for your specific model. Or start a new thread, with your model name in the title of the thread, and state your problem.
Thanks and Good Luck |

Thanks to everyoone who suggested cleaning the bulb and mirror. I found an HP PCS 750 in the trash and took it home only to find that it had the scanner failure problem. I knew the getting it repaired would cost too much to make it worth while, since I already bought new ink and a power supply (I didn't find those in the trash). I was just about to cut my losses and put it back where I found it. I'm am going to try this as soon as I get home. And, YES, HP should put this info in the trouble shooing section, but I'm sure the will now since the 750 is a discontinued model. |

Remove the lid by holding it straight up and pull up and out. It should come out easily. Then use a T10 (#10) Torx screwdriver to open up the top two screw holes toward the back of the unit. Pull the lid forward while grasping the right front side first and pulling toward you and then pull the left front side. Carefully lay the glass frame over the the right (flip it over to your right) and hold it being careful not to put too much strain on the cable or just pull the ribbon cable out of it's slot under the glass top/plastic frame and set the top aside but you do not have to if you are careful. You may want someone to hold it in place for you. I just used the front right screw bottom to hold it on the plastic edge of the unit. Take a flat screw driver and put it in the large slot of the black plastic flap toward the front and pop it up to your right. Angle the blade of the screw driver so it it pointed toward the right side of the unit. Do the same for the big slot toward the back. The black cover should pop off. Reassemble the unit. Leave the black cover out of the unit and store it but I doubt you will need it again. Mine works just fine now. |

I have a d155xi with scanner failure and just want to disable the scanner diagnostics or even the scanner (in order to eliminate the diagnostic error message), so that I can see messages regarding the printer components, which is all I use on this machine anymore.

I just revisited this thread. My PSC 750 has had the scanner error twice. Once about 3 years ago and again in the last week. Both times I pulled the scanner carrier out as the directions in this thread state and cleaned the mirrors. Pay attention to the orientation of the mirrors. Clean both sides, some only reflect off of one side. I have not left off the black cover, I put it back on both times. My printer is in an area that does get a lot of dust, etc.. Suggestion---save this thread for later use, its easier to find 3 years down the road. |

I have had this very same problem now for over a year...finally I found the fix.
Step one. download the latest software for the 700 series PSC. Then remove completely any existing drivers and the old software for the 700 series. Disconnect your anti virus and firewall, disconnect the PSC from the printer, plug the unit into a wall socket and not a surge protector. Leave unit without power for thirty seconds and then plug into the wall. Allow unit to set up...at this point your unit will most likely still be flashing the same tired message of "Scanner Failure". ingnor it...
Run the software and latest driver from the HP website that you previously downloaded. Follow the prompts for it and the set up should be complete...you do not need to register this so skip that part. Now and this is important...Pressing and holding the power button for at least one second, release and press again....and immediately go to Printer's desktop icon and click on it and click on scan... you must complete this task before your unit starts to blink again... repeat until you get it right...the the unit will wait for next scan...scan a few more times and allow unit to reset....
This works until you have a power failure and then you may have to do it again...
I'm a scanning fool once again and I had been ready to kick it to the curb. |

I find this hard to believe but I did was was sugessted:
There is some stuff that can be done for this, but if it doesn't work, you'll probably end up needing to contact technical support, and having them service the unit.
1) Make sure the unit is plugged into a wall and not into a surge protector.
2) If that doesn't work, try a reset. For the PSC750s, unplug it, ahold down Cancel and the Left Arrow buttons, and plug back in.
Well it worked I have been coping ever since. Thank you all I was ready to go buy a new wireless unit. |

Thanks so much to all and Jeffery Conklin for helping me fix my printer. I did all the steps in order. Everything work great except for one thing. My black is not printing. I know it is not out of ink but will replace it if there is not somthing I can check... any ideas???

My PSC 750 would work for about 10 minutes and then if I tried to scan or copy, the scanner failure message would appear. The error also occurred when I tried to copy without the printer being connected to the PC, so it was not a driver problem. I tried the suggested power fix without success. I then followed Jeffery Conklin's exellent instructions and removed the black plastic cover. I did not clean the mirrors as they were still clean. It's as if I now have a new printer. Thank you to everyone who has contributed and in partiucular to Jeffery. |

I am having a scanner failure issue (and have been for months). I am unable to get the glass part off of the unit. There was a mention of disassembly in pictures, but I do not see a link. If anyone has a link to them, it would be greatly appreciated. Thanks in advance. I have tried all of the new driver install, power off, plug into a wall, resets, etc.. |

Way back when there were pictures of the rebuild but if memory serves me correct they got removed (By HP????...I think that was the rumor. I dont know for sure.). At one time I viewed them but in my recent search I could not locate them. Hopefully someone else has them or remembers where they are. As far as not being able to remove the glass my question is what PSC, what piece of glass. I AM NOT a HP PSC guru but I have taken apart my PSC 750 twice with no ill effects and corrected the Scanner Failure problem. If you have a PSC 750 my advice is to follow the post written by Jeffery Conklin on Mar, 30 2006 in this thread. If you are still having trouble (with a 750) I should be able to take some pics of mine for you (it probably needs cleaning again). Put the scanner in a place you can work on it with good lighting and take your time. I have tried every software fix, every non mechanical fix to no avail. I also have had power failures since the cleaning and everything works fine. Good Luck! |

Same thing "Scanner Failure"
Here's what I did...
Tried the Left arrow / cancel buttons at power on thing & no dice
So
* I powered off,
* unplugged from PC and power,
* took the top off,
* got access inside (thanks to the others that got me that far)
* slowly/manually pushed the light carriage all the way to the left (furthest from home position),
* snapped the top back on
* powered on still failed
* pulled power momentarily (like 1 sec)
* plugged back in and the carriage began to move to the right
* it went about 1/5th of the way & returned
* the it did it again and went further
* then went back
* then back to the right, BUT all the way:-)
* back and forth around home a little
* AND COOL! it worked again :-)
[obviously no guarantee, push the carriage was my last hope] |

Mine was also very erratic after working very well for well over a couple of years. This thread got me thinking differently. so i unpowered it and blew it out. Powered back up and badabing... it started working again. So obviously gunk is the enemy. Forget the driver thing. I tried that angle several times especially after Driver Doctor told me my driver was out of date but HP said differently. |

I tried everything in the HP troubleshooting short of taking it my D145 in for service and nothing worked until I read in this forum to hold the cancel and left arrow buttons down while plugging the power cord back in. This worked for me this time. Will have to see if this has fixed it for a while. I did notince my scanner glass is awful foggy so I might get to cleaning that soon. |

I forgot to mention my initial problem. Scanner failure, turn power off then back on again..... after warmup when copy or printing. |

Thanks for all the info. Cleaning the lens (aka the "eye", which is a camera-like small lens facing left) helped me. |

I too was having problems with scanning and I found a thread that mentions using a surge protector is a problem. (for a different scanner but I thought - what the heck - I'll try ANYTHING!) Apparently they have a tendancy to prevent ENOUGH electricity into the scanning parts - so I plugged it directly into the wall outlet and it not only works but it's faster! It obviously was struggling now that I see how quickly the scan window comes up!
Crossing my fingers that this solves your problem too!

I fixed this also by removing the black cover. To clarify on the removal of the black cover. There is a larger square hole and smaller rectangular hole on each side of the cover. Place the screwdriver in the smaller rectangular hole on each side to remove the cover. |

For the second time I had a HP psc 750 Scanner Error, "Failure to Initialize" again. The last time was in Nov 2006. In 2006 I removed the cover and left it off, and cleaned the mirrors the best I could. This time all I did was clean the mirrors and It has been working fine for a week or so. This time I used Jeffery Conklin's instructions in an above post to disassemble the scanner, Big Help. I also slid the center mirror from under the clips, to give better access to the other mirrors. This time I cleaned the mirrors much better than the first time in 2006, because I could reach them better, after removing the center mirror. I reinstalled the center mirror by holding it very carefully between the 2 tabs at each end of the mirror mount and slid the clips up into place until they clicked into a locked position. Because of everyone's great input my HP psc 750 is now in it's third life. Thanks to everyone, especially Jeffery Conklin and those who suggested removing and leaving the cover off. Great site |

Thread is over 6 years old and still going strong. Amazing. I followed Jeffery Conklin's instructions posted on Mar 30, 2006 and just copied something for the first time in a long time. Cleaned the mirrors and glass and left the black plastic cover off. Thank you and God bless everyone in the whole wide world except HP. |

When this happens to me, I notice the lamp will not park in home position.
To have the lamp parked in home position and operate scan again successfully:
Power off and then power on
Press copy black and then press Cancel
The lamp will move to and fro and then park home
Scanning is possible again |

Some years on . . . we have had this same recurring problem - "scanner failure". We can print test pages but aligninig cartridges requires the scanner to scan the test page. We have no idea how to correct the scanner failure - light is working, it does move but it just seems to default to scanner failure and the rest of the system does not operate. If anyone has figured this out, please let me know, thanks |

To Ric, Gary ST and anyone trying to find a fix for "scanner failure error message":
I have a hp psc 750xi. I bought it in 2000 and have never had it serviced. When I first received "scanner failure" I thought that might be the reason, but the only problem I had ever noticed before was a slight squeak when the print carriage moves one direction. Now, my printer was working fine for printing from the internet, email and MS word/excel program, but would not print/scan/copy from the flatbed.
I found this website and began making attempts at what worked for others, to no avail! But somewhere I had read something about room temperature and my printer had been in storage for a month (although during summer months), I also kept my computer room at about 58-60 degrees. So I brought a thermometer in here and turned the heat up until it reached 68 degrees and kept it that way for about 24 hours.
Well, low and behold. It works and has been working ever since. I hope it works for some of you to! Thanks! |

I had the same problem. As stated in the emails above, the simplest solution is to try plugging the printer directly to a wall outlet. Worked for me! |

Well, in the past three weeks, each time I have turned the heat down even sometimes only 3 degrees, in my office/computer room, my HP 750xi has begun giving the scanner failure error again. I turned it back up and have left it there and all works just fine! No more error messages! Nothing else ever worked! Thanks! |

As vvan said, the problem is that the head lamp is not in the correct position when starting scanning.
So the problem can be fixed if you can move it back to its position.
Just Press "Black copy" button and "Cancel" right away. The machine will adjust the position of the head lamp. Try copying again and you'll see the 'magic' |

I'm in the same boat as most of you. I dismantled the top end and got right in to the scanner body today. Just remove the black lid and don't ask questions as described in this thread with a small scewdriver. The lid will come off after pinching action is felt through the rectangle area as you lift on the right side of the lid. Repeat this on the left carefully. Once the "Hat" is off you have complete access to the lenses which will probably show evidence of grit. Clean all visible lenses with isopropyl, q-tips and wipe with clean lint free cloth. Reassemble and calibration will happen once you push the button to copy. Worked on the first try after many painful software and hardware attempts! If your scanner was working and then prompted with "Scanner Failure" whenever, I strongly recommend this solution! Happy New Year PSC 750! |

Hi,
It all started by PSC 2210 asking me to check cartridge. After checking and cleaning and getting always the same message, I bought and inserted a new black (56) cartridge. Printer asked me to press Enter to align cartridges, and after each pressing I got consecutive messages: Report waiting, press Enter to align, occupied, press enter to align, printing (but nothing prints out) press enter to align, occupied, then Scanner failure switch off and on. I switch off/on, same endless loop.
In HP knowledge base found "Press enter to Align Cartridges" document that says how to bypass the cartridge alignment: Press and hold the Setup button and press the Options button.
Done, and this stopped the endlesss loop of "Preess Enter to Align Cartridges", but printer still did not print, copy nor scan, connected or not to the W2000 PC.
Had online chat with HP technical support, they made me try semi and full resets (# and 3 / # and 9, also #and 6) unplugging, on/offs etc et finally declared there must be a hardware error and I have to buy a new printer.
Read all messages on this site and tried to print empty Word file etc, still "Scanner failure" and no print.
on HP Customer Care . HP PSC2410 Photosmart All-in One Printer found document "How to clean the Scanner Glass" , with pictures describing how to dissasemble front cover. I did it and WOW ! :
found scanner traction motor small power plug had jumped out. This explains why scan head had never moved after failure appeared. I plugged it in, checked it sits in OK, re-assembled the unit and ALL WORKS OK !
This Forum is a great place to find the solution, so thanks to all those giving inputs to it! |

Hi
Thanks to all. I had the same problem on a psc 750 which I had been given and removing the black cover fixed it.
