PROBLEMS

Vertical lines
If black vertical streaks appear on the page:
The drum inside the toner cartridge has probably been
scratched. Install a new toner cartridge.
Gray background
If the amount of background shading becomes unacceptable,
the procedures below may fix the problem.
Change to a lighter weight pages. See “Paper Specifications”
on page E.3.
Check the printer’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
“Installing the Toner Cartridge” on page 2.4.
Toner smear
Clean the inside of the printer. See “Cleaning the Inside” on
page 5.5.
Check the paper type and quality. See “Paper Specifications”
on page E.3.
Remove the toner cartridge and install a new one. See
“Installing the Toner Cartridge” on page 2.4.
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 page 5.7. After the printout, if you
still have the same problems, install a new toner cartridge.
See “Installing the Toner Cartridge” on page 2.4.
• Parts of the printer 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.
