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 print cartridge assembly for contamination
or damage. Correct as necessary.
Check continuity between the cable (DEV, TAR, and doctor blade) connection PCN3 and on
the contact tips below the print cartridge assembly.
• If continuity fails, call the next level of service.
LVPS/HVPS board
Controller card
Miscellaneous cables
With the printer off, disconnect the LVPS/HVPS cable from J19 on the controller card.
Turn the printer on, and verify +24 V dc on pins 8 and 9 of the cable.
Verify ground on pins 7, 12, and 14.
• If the voltage is incorrect, replace LVPS/HVPS board.
• If grounds are incorrect, check ground paths.
• Check confinuity in the cable. Replace the cable if necessary.
• If voltage is correct and the toner electrodes are good, replace the controller card.
• See the “LVPS/HVPS service check” on page 2-20 and the “Controller card service
check” on page 2-17, if necessary.
FRU Action
Toner cartridge (not a
FRU)
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.
If the toner cartridge and PC Kit are installed correctly, try a new PC Kit first and then toner
cartridge.
LVPS/HVPS
Controller card
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 PCN3. Clean as necessary.
If this does not correct the problem, replace the following FRUs one at a time in the order
shown:
• LVPS/HVPS board (See “Black page” on page 3-25 for pin values.)
• Controller card
