Solution

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 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.

Toner smear	• 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.
	• Install a new toner cartridge.

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 6.5). 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.
