Make sure that the color imaging unit stays covered until immediately
before installing it in the printer. Exposure to light for more than 45
seconds can damage the color imaging unit.
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.
The cleaning pad may be dirty with toner. Replace the cleaning pad
(see the supplement for supplies provided).
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.
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.
