Problem Solution
If the amount of background toner shading becomes
unacceptable, the procedures below may help to clear the
condition:
• Change the paper to a lighter basis weight. See “Paper
Specifications” on page A.2 .
• 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.

• Clean the inside of the printer. See “Cleaning the Inside”
on page 6.4 .
• Check the paper type and quality. See “Paper
Specifications” on page A.2 .
• Try installing 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 every 95 mm or 38 mm on the page, print a
cleaning sheet several times to clean the cartridge (see
page
6.5 ). After the printout, if you still have the same
problems, install a new toner cartridge.
• Parts in 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.
