Streaks or spots

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.
Make sure that the imaging unit stays covered until immediately
before installing it in the printer. Exposure to light for more than
45 seconds can damage the imaging unit.
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 (you can print
any of the Help Pages in the front panel menu).
Light, wavy, vertical streaks indicate a dirty or used corona wire.
Clean the corona wire; if the problem persists, replace the
corona wire.
