Service Manual
Action
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 try a new toner cartridge.
Check the contacts for correct installation and contamination where
contact is made between the print cartridge assembly and LVPS/
HVPS board. 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
• Controller card
Action
Remove the toner cartridge assembly, and gently shake the
assembly to evenly distribute the toner.

Action
The charge roll may have an unbalanced pressure against the
photoconductor (PC) drum.

bearing assemblies should support the transfer roll, applying even
pressure to the PC drum.
Replace the transfer roll assembly if the springs or bearing show
signs of damage or fatigue.
Inspect the transfer roll for signs of wear, damage, or contamination.
Replace as necessary.

Make sure recommended paper is being used. Check the media type
and texture setting's on the MFP and in the driver.
