Vertical lines
If black vertical streaks appear on the page:
The drum inside the toner cartridge has probably been
scratched. Remove the toner cartridge and install a new one.
See “Replacing the Toner Cartridge” on page 8.9.
Gray background
If the amount of background shading becomes
unacceptable:
Change to a lighter weight pages. See “Paper Specifications”
on page A.6.
Check the machine’s environment; very dry (low humidity) or
high humidity (higher than 80% RH) conditions can increase
the amount of background shading.
Remove the old toner cartridge and install a new one. See
“Replacing the Toner Cartridge” on page 8.9.
Toner smear
Clean the inside of the machine. See page 8.4.
Check the paper type and quality. See “Paper Specifications”
on page A.6.
Remove the toner cartridge and install a new one. See
“Replacing the Toner Cartridge” on page 8.9.
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the page
at even intervals:
• The toner cartridge may be damaged. If a repetitive mark
occurs on the page, print a cleaning sheet several times to
clean the cartridge; see “Cleaning the Drum” on
page 8.11. After the printout, if you still have the same
problems, remove the toner cartridge and install a new
one. See “Replacing the Toner Cartridge” on page 8.9.
• Parts of the machine may have toner on them. If the
defects occur on the back of the page, the problem will
likely correct itself after a few more pages.
• The fusing assembly may be damaged. Contact a service
representative.
