Trouble
Streaks or spots
The back of the
printed page
appears dirty.
The print quality of
a transparency is
poor.
Corrective Action
Most spots are caused by fingerprints or dust
introduced into the printer while installing the color
imaging unit or loading media.
Make sure that the surface where you unpack the
color imaging unit, paper, and transparencies is free
of dust. Keep supplies in a covered area or a closed
box.
Make sure that the color imaging unit stays covered
until immediately before installing it in the printer.
Exposure to light can damage the color imaging unit
and will produce light streaks or faded prints.
Do not touch the right side or underside of the color
imaging unit; fingerprints affect print quality.
Make sure that the paper or transparency film is
clean.
Make sure that you handle the media on the outside
edges to avoid fingerprints.
To get rid of fingerprint spots, print a few prints.
Toner particles have contaminated the transfer
roller. This can happen if the printed image is larger
than the media (for example, when printing on
envelopes). Run 10-20 prints to clean the transfer
roller.
There is a defect on the coated surface of the
transparency. Print on the other side.
