Phaser 540 Color Printer
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.
