Toner smudges
Remove the toner cartridge from the printer and shake
it a few times. If the problem persists, replace the
cartridge.
Clean the fuser unit rollers.
Clean the transport roller.
Install a new cartridge if needed.
White spots at intervals
Replace the drum cartridge.
Verify that a clear image is being placed on the drum
by printing a document and opening the printer cover
before the document completes printing. At this point,
remove the drum and check for a clear image on
the drum. If there is a clear image on the drum, the
problem could be caused by poor image transfer.
Replace the image transfer unit and/or the main control
board.
If the image is not clear, replace the print head and/or
the drum.
