Black page
Note:
Incorrect laser exposure or incorrect charging of the photoconductor causes an all black page. Always
verify the same results from a different print cartridge assembly and developer before proceeding.
Heavy background
Poor development or poorly charged toner particles cause excessive background. This is more noticeable as
the toner cartridge nears end-of-life.
FRU
Action
Toner electrodes (not
a FRU)
Check the three rearward electrodes below the toner cartridge assembly for contamination,
damage, or a short to ground. Correct as necessary.
Check continuity between the cable (DEV, TAR, and doctor blade) connection PCN3 and
on the contact tips below the toner cartridge assembly.
• If continuity fails, then call the next level of service.

5 V dc on pins 1, 3-5, 11, 13, and 15.
Verify ground on pins 10, 12,14, 16, and 18.
• If any of the values are incorrect, then replace LVPS/HVPS board.
• If the grounds are incorrect, then check ground paths.
• Check continuity in the cable. If the cable is bad, then call the next level of support.
• If the values are correct and the toner electrodes are good, then replace the controller
board.
• See the
“LVPS/HVPS service check” on page 2-39

PC Kit (not a FRU)
Check the toner darkness setting in the driver. Try a lower setting.
Make sure the toner cartridge and PC Kit are correctly installed and the high voltage
contacts are clean.

toner cartridge.
LVPS/HVPS

between the print cartridge assembly and spring contacts which connect to the LVPS/HVPS
board at CN203. Clean as necessary.

order shown:
