Solving Print Quality Problems

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”.

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.
