Dirt on the top edge or back of the paper
Symptom
Check toner contamination in various
parts.
Check the transfer roller.
Suggested remedy
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 Process 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.
