Dirt on the top edge or back of the paper
Incorrect printing registration
Check point Suggested remedy
Check toner contamination in
various parts. • Dirty edges and back of the paper can be caused by toner
accummulated 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.
Check the transfer roller. • If the transfer roller is contaminated with toner, clean
the transfer roller using a vacuum cleaner; or by continu-
ously printing a low-density page until the symptom has
faded away.
Check point Suggested remedy
Wrong application manipula-
tion • Check driver setting. If using Prescribe commands,
review that the proper syntax is followed.
Check the paper size sensor
in the paper cassette. • Check switches on KP-904 and KP-910 boards. Refer to
the following section.
