Disconnect the printer cable

that you know works. Finally,
try a new printer cable.

driver was selected.
Check the application’s
printer selection menu to
ensure that your machine is
selected.

file as an image.
Condition Possible cause Suggested solutions
Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly,
you may notice a reduction in print quality. See the table below to clear
the problem.
Condition Suggested solutions
Light or faded
print
If a vertical white streak or faded area appears
on the page:
• The toner supply is low. You may be able to
temporarily extend the toner cartridge life.
See page 10.4. If this does not improve the
print quality, install a new toner cartridge.
• The paper may not meet paper
specifications; for example, the paper is too
moist or too rough. See page 5.1.
• If the entire page is light, the print resolution
setting is too low. Adjust the print resolution.
See the help screen of the printer driver.
• A combination of faded or smeared defects
may indicate that the toner cartridge needs
cleaning.
• The surface of the LSU part inside the
machine may be dirty. Clean the LSU. See
page 10.2.
Toner specks
• The paper may not meet specifications; for
example, the paper is too moist or too
rough. See page 5.1.
• The transfer roller may be dirty. Clean the
inside of your machine. See page 10.2.
• The paper path may need cleaning. See
page 10.2.
Dropouts
If faded areas, generally rounded, occur
randomly on the page:
• A single sheet of paper may be defective.
Try reprinting the job.
• The moisture content of the paper is uneven
or the paper has moist spots on its surface.
Try a different brand of paper. See page 5.1.
• The paper lot is bad. The manufacturing
processes can cause some areas to reject
toner. Try a different kind or brand of paper.
• Change the printer option and try again. Go
to printer properties, click Paper tab, and
set type to Thick. Refer to the Software
Section for details.
• If these steps do not correct the problem,
contact a service representative.
