Light print
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 you are using recommended print
media (see media types and sizes in the
User’s Reference).
• Use MarkVision 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. See
“Light print” on page 2-103.
Toner smudges appear
on the front or back of
the page.
• Make sure the paper is straight and
unwrinkled.
• Replace the PC Kit and recheck before
replacing the toner cartridge. See “Toner on
back of page” on page 2-104 for more
information.
