Light print
See “Light print” in “Troubleshooting”.
The toner cartridge may be getting low on toner:
• Remove the toner cartridge and print cartridge assembly.
• Shake it from side to side to redistribute the toner.
•
Reinstall it, and recheck for condition.
• Make sure to use the recommended print media (see media types and
sizes in the User’s Guide).
• Use MarkVision™ Professional to define the custom type setting for
media type, media texture, or media weight.
• The toner cartridge or PC Kit may be defective. Replace the PC Kit first,
and recheck.
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 machine 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
the page.
• Make sure the media is straight and unwrinkled.
•
Replace the PC Kit, and recheck before replacing the toner cartridge.
See “Toner on back of page” in “Troubleshooting” for more
information.
