Perform the Half Self Test Check is to determine which process is malfunctioning. Perform the test as follows: 1 Initiate an 05 SELF TEST.
2 Open or switch OFF the printer after the paper advances halfway through the printer (the leading edge of the paper should advance at least past the Transfer Charge roller). Ideally it will have stopped halfway past the toner cartride so that there is still a partial image on the cartridge.
3 Remove the Toner Cartridge.
4 Open the Toner Cartridge's drum shield to view the drum's surface.
If a dark and distinct toner image is present on the drum's surface, assume that the first four functions of the electro-photographic process are functioning, and troubleshoot the failure as a transfer problem. If NO image is present on the photoconductive drum, perform these checks
Drum Rotation Functional Check
The photoconductive drum, located in the Toner Cartridge, must rotate for the print process to work. The photoconductive drum receives its drive from the Main Motor gear train. To verify whether the drum is rotating:
1 Open the printer's Top Cover Assembly.
2 Remove the Toner Cartridge. Open the Toner Cartridge's drum shield (cover) to view the photoconductive drum.
3 Mark the gear with a felt-tipped marker. Note the position of the mark.
4 Install the EP Toner Cartridge, and close the Top Cover. The 1-second startup sequence should rotate the drum enough to move the mark. Open the printer, and inspect the drum. Verify that the mark moved. If the mark did not move, inspect the gear train to ensure that it is meshing with the Toner Cartridge gears. If the drive gears appear functional, and the drum does not move, replace the Toner Cartridge.
Note This test is especially important if refilled Toner Cartridges were used.
High voltage Power Supply Check
Are the connectors for the Primary Charge roller, Drum Ground, Developing Bias, Toner Level Sensor damaged, corroded, dirty, or missing? Also check the Toner Cartridge. Visually inspect each item. If any are damaged, correct as necessary. Replace the High Voltage Power Supply if the connection is not repairable. Check that all wires are connected to their respective terminals.
Are the HVPS connections bent or broken? Clean the terminals with alcohol only.
