Print quality problems
Problem Solution
Light or faded print If a vertical white streak or faded area appears:
• The toner supply is low. You may be able to temporarily extend the toner
cartridge life. See page 64.
If this does not improve the print quality, install a new toner cartridge.
• The paper may not meet paper specifications (for example, paper is too
moist or too rough). See page 22.
• If the entire page is light, the print resolution setting is too light. Adjust the
darkness and content. See page 45.
• A combination of faded or smeared defects may indicate that the toner
cartridge needs cleaning. See page 68.
Toner specs • The paper may not meet specifications (for example, the paper is too
moist or too rough). See page 22.
• The paper path may need cleaning. See page 63.
Dropouts If faded areas that are 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 21.
• The paper lot may be defective. The manufacturing processes can cause
some areas to reject toner. Try a different brand of paper.
• The toner supply is low. You may be able to temporarily extend the toner
cartridge life. See page 64.
If this does not improve the print quality, install a new toner cartridge.
• If these steps do not correct the problems, contact a service
representative.
Vertical lines If white or black vertical streaks appear on the page, the drum inside the
toner cartridge has probably been scratched. Install a new toner cartridge.
See page 65.
