Make sure the toner cartridge and PC Kit are installed correctly and that the toner cartridge
is not low on toner.
If the problem continues, then install a new toner cartridge.
Recheck condition before replacing PC Kit, if necessary.

LVPS/HVPS card
Check the transfer roll for signs of toner buildup and contamination.
Inspect the HVPS contact (transfer roll) for contamination.
Verify the high voltage cable is plugged into the LVPS/HVPS.
If all components appear free of contamination, then replace the following FRUs one at a
time in the order shown:
• Transfer roll
• LVPS/HVPS card

Banding appears as light or dark horizontal lines on a uniformly gray page or on a page with
a large area of graphics. Banding is primarily due to a variation in the speed of the media as
it feeds through the printer, especially in the developer and transfer process. It may also be
a result of overly dry or moist environments.
With the printer off, check to make sure that the laser beam is not blocked.
Inspect the toner cartridge and paper feed components, especially the drive coupler and
drive gears for debris, binds, or damage.
FRU Action
Photoconductor kit (not
a FRU)
Print a menu page from the Menu Settings Page in the Reports menu.
Inspect the overall paper path for signs of spilled toner.
Gently clean the contaminated areas with a soft cloth.
Fuser Inspect the fuser for signs of contamination.
Replace the fuser as necessary.
Transfer roll A transfer roll contaminated with toner can cause toner to transfer to the back of pages.
Inspect the transfer roll for contamination and its cable for continuity.
HVPS or engine board Loss of the proper high voltages can cause excessive toner to contaminate the transfer
roller. None of these voltages can be measured, but the contacts and continuities can be
checked. To check the lower voltage, see J502 on the wiring diagram. Replace the LVPS/
HVPS or controller board as necessary.
