Problem
Solution
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
• Check the printer’s environment; very dry (low humidity)
or high humidity (higher than 80% RH) conditions can
increase the amount of background shading.
• Install a new toner cartridge.

• Check the paper type and quality. See “Paper
Specifications” on page
• Install a new toner cartridge.
Toner smear
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
). After the printout, if
you still have the same problems, install a new toner
cartridge.
• 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.
