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.

Gray background

• 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 the

cleaning sheet several times to clean the cartridge (see

page 6.5). 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.
