PROBLEM SOLVING
Problem
Solution
• The paper may not meet specifications (for example, the
paper is too moist or too rough). See “Paper Specifications”
on page A.2.
• The transfer roller may be dirty. See “Cleaning the Inside”
on page 6.4.
• The paper path may need cleaning. See “Cleaning the
Inside” on page 6.4.
Toner specs
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 “Paper Specifications” on page A.2.
• 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 cartridge may be defective. See “Vertical
repetitive defects” on the next page.
• If these steps do not correct the problems, contact a
service representative.
Dropouts
If black vertical streaks appear on the page:
• The drum inside the toner cartridge has probably been
scratched. Install a new toner cartridge.
