Make sure that the media thickness switch is set
correctly for the installed media( +P. 29). Make sure that you use a high-quality laser paper: 
60-105 g/m
2(16-28 lbs.) paper in the media trays and 
75-165 g/m2(20-44 lbs.) paper in the multi-purpose tray.
Use only recommended transparencies( +P. 157). 
We cannot guarantee the results of other transparencies.
TroubleCorrective Action
Frequent media jams.
Care and Maintenance
Fan the paper or transparencies before installing them in
their respective trays; this is especially important for
transparencies because they tend to stick together.
Make sure that you have loaded paper in the paper tray
and transparencies in the transparency tray.
Make sure that the media is installed under the hooks at
the front of the media tray.
If printing on transparencies and your printer has a 2nd
Cassette Feeder, make sure that the transparency tray is
installed in the upper or middle tray slot.
Clean the paper-pick rollers 
( +P. 99 for instructions).
If you are using media that is 105 g/m
2(28 lbs.), check if
the Face Down media output setting is selected in the
driver. If it is, change the setting to Face Up.
Make sure that the media is installed under the hooks at
the front of the media tray.
Do not overfill the media tray, as indicated by the red line
on the right side of the tray.
Clean the paper-pick rollers
( +P. 99 for instructions). Frequent paper-
picking errors.
nMedia problems
Corrective Action
Make sure that the correct size media is in the media
tray.
nProblems with image size and position
Check your application for correct image sizing. Off-set images.
Check your application for image sizing. Cut-off images.
Trouble 
						

							126
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. Print the Color Calibration Page from the Color
Calibration menu in the printer panel. Check the density
settings for each color and compare them to the
examples on the Color Density Samples. Refer to Setting
the Color Density on page 54for instructions on
comparing and setting color density.
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.
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.
Corrective Action
Make sure that you use a high-quality laser paper: 
60-105 g/m
2(16-28 lbs.) paper in the media trays and 
75-165 g/m2(20-44 lbs.) paper in the multi-purpose tray. Make sure that the toner cartridges are installed correctly. Make sure that the imaging unit stays covered until
immediately before installing it in the printer. Exposure to
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.
Trouble
Image is very faded or
pieces of the image
are missing; toner on
the page is loose.
Streaks or spots
The back of the
printed page appears
dirty.
