• Dirty edges and back of the paper can be caused by
toner accumulated on such parts as the paper chute,
paper transportation paths, the bottom of the developer
unit, and the fuser inlet. Clean these areas and parts to
remove toner.
• If the transfer roller is contaminated with toner, clean
the transfer roller using a vacuum cleaner; or by
continuously printing a low-density page until the
symptom has faded away.
