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.
LVPS/HVPS board
Controller board
Miscellaneous cables
With the printer off, disconnect the LVPS/HVPS cable from J502 on the controller board.
Turn the printer on, and verify +24 V dc on pins 17 and 19 of the cable.
Verify +5 V dc on pins 1, 3, 5, 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 2-26 and the “Controller board
service check” on page 2-23, if necessary.
FRU Action
Toner cartridge (not a
FRU)
Photoconductor kit (not
a FRU)
Check the toner darkness setting in the driver. Try a lower setting.
Make sure the toner cartridge and photoconductor kit are correctly installed and the high
voltage contacts are clean.
If the toner cartridge and photoconductor kit are installed correctly, then try a new
photoconductor kit first and then toner cartridge.
LVPS/HVPS
Controller board
Check the contacts for correct installation and contamination where contact is made
between the print cartridge assembly and spring contacts which connect to the LVPS/HVPS
board at CN203. Clean as necessary.
If this does not correct the problem, then replace the following FRUs one at a time in the
order shown:
• LVPS/HVPS board (See “Black page” on page 2-32 for pin values.)
• Controller board
