Print Quality Problems
Problem Action
Print is too light, or printed
images or characters have voids
or dropouts. Be sure you’re using recommended
paper or other media. Use media from a
new package.
Be sure you have selected the correct
Paper Type setting for the media you’re
using.
Be sure the affected print unit is
completely installed in the printer.
Set Toner Saver Off from the Color Menu.
Clean the head LEDs.
If you suspect a toner cartridge is low on
toner, remove the appropriate print unit
and gently shake it back-and-forth to
distribute the toner evenly. Reinsert the
print unit and try printing the job again.
Replace the affected toner cartridge.
Replace the photoconductors. If only
black print appears light, you can replace
just the black photoconductor. If one of
the colors prints too light, replace all three
of the color photoconductors. If you still
have the problem, go to
“Partial
Darkness or Lightness” on page 2-44 .
Colored lines, streaks, or
smudges appear on the printed
page, or print appears blurred or
unclear. Replace the photoconductors. If the
problem only occurs when printing black,
you can replace just the black
photoconductor and fuser coating roll. If
the problem occurs when printing one of
the colors, replace all three of the color
photoconductors. If you still have the
problem, go to
“Black Line” on
page 2-42 .
