light can damage the imaging unit and will produce light
streaks or faded prints.
Most spots are caused by fingerprints or dust introduced
into the printer while installing the imaging unit or loading
media.
Make sure that the surface where you unpack the
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 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.
Prints have dull, faded
colors.
