Solving Print Quality Problems
Dirt inside of the printer or improper paper loading may reduce
the print quality. See the table below to troubleshoot the
problem.
Problem Solution
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 “Redistributing the Toner”
on page 6.5. If this does not improve the print quality, install a
new toner cartridge of faded color.
• The paper may not meet paper specifications (for example,
the paper is too moist or too rough). See “Paper
Specifications” on page D.4.
• A combination of faded or smeared defects may indicate that
the toner cartridge needs cleaning. See page 6.31.
• The surface of the LSU may be dirty. Clean the LSU. See
page 6.30.
Toner specs
• The paper may not meet specifications (for example, the
paper is too moist or too rough). See “Paper Specifications” on
page D.4.
• The transfer roller or the paper path may be dirty. See
“Cleaning the Inside of the Printer” on page 6.31.
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
“Paper Specifications” on page D.4.
• The paper lot is bad. The manufacturing process can cause
some areas to reject toner. Try a different kind or brand of
paper.
• The toner cartridge may be defective. See “
Vertical repetitive
defects
” on the next page.
• If these steps do not correct the problems, contact a service
representative.
