Condition Possible cause Suggested solutions Solving print quality problems
Dirt inside of the printer or improper paper loading may reduce print
quality. See the table below to troubleshoot problems.
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 cartidge life. See
page 8.3. If this does not improve print quality,
install a new toner cartidge.
• The paper may not meet paper specifications
(for example, the paper is too moist or too
rough). See page 5.3.
• If the entire page is light, the print resolution
setting is too light or toner save mode is on.
Adjust the print resolution and toner save
mode in the printer properties. See the
Software Section .
• A combination of faded or smeared defects
may indicate that the printer needs cleaning.
See page 8.1.
• The surface of LSU may be dirty. Clean the
LSU. See page 8.1.
Toner spots
• The paper may not meet specifications (for
example, the paper is too moist or too rough).
See page 5.3.
• The transfer roller or paper path may be dirty.
See page 8.1.
Dropouts
If generally rounded, faded areas 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 5.3.
• The paper lot is bad. The manufacturing
processes can cause some areas to reject
toner. Try a different kind or brand of paper.
• The toner cartidge may be defective. See
“Vertical repetitive defects” on the next page.
• If these steps do not correct the problems,
contact a service representative.
