• The toner supply is low. You may be able to temporarily
extend the toner cartridge life. See “Redistributing Toner”
on page 5.3. If this does not improve the print quality,
install a new toner cartridge.
• The paper may not meet paper specifications (for
example, the paper is too moist or too rough). See “Paper
Specifications” on page 7.25.
• 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
page 4.16 and 4.8 respectively.
• A combination of faded or smeared defects may indicate

cause some areas to reject toner. Try a different kind or
