Blurred characters
Blurred images, including characters, are usually caused by a defective printhead.
Vertical white lines
See “Vertical streaks below.
Vertical white lines may be caused by the laser beam, which may be partially blocked. With
the printer off, clear the path or clean the lens. The toner cartridge or fuser may be
defective. Try a different toner cartridge. Inspect the fuser at its entry for debris.
Toner smudges appear
on the front or back of
