Print quality problems
Trouble Corrective Action
Prints have dull,
faded colors. Adjust or calibrate colors. See Chapter 7 “Color
Calibration”.
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.
Make sure that the toner cartridges are installed
correctly.
Make sure that you use a high-quality laser paper:
60–105 g/m2 (16-28 lbs.) paper in the media trays
and 75–165 g/m2 (20–44 lbs.) paper in the multi-
purpose tray.
Image is very
faded or pieces of
the image are
missing; toner on
the page is loose.
When using the multi-purpose tray, make sure that
you have selected the correct media type in the
driver or in the Menu mode of the printer panel.
Streaks or spots 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.
