Problem

Possible Cause and Remedy

Vertical repetitive defects		If marks repeatedly appear on the printed side of the page at
		even intervals:
		• The toner cartridge may be damaged. Print a cleaning
	AaBbCc
		sheet several times by cleaning the OPC drum (see
	AaBbCc
		page 6.2). After the printout, if you still have the same
	AaBbCc
		problems, install a new toner cartridge.

	AaBbCc	• Parts in the machine 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.
Background scatter		Background scatter results from bits of toner distributed on
		the printed page.
		• The paper may be too damp. Try printing with a different
	A
		batch of paper. Do not open packages of paper until
		necessary so that the paper does not absorb too much
		moisture from the air.
		• If background scatter occurs on an envelope, change your
		printing layout to avoid printing over areas that have
		overlapping seams on the reverse side. Printing on seams
		can cause this problem.
		• If background scatter covers the entire surface of a printed
		page, adjust the print resolution through your software
		application or the printer properties.
Misformed characters		• If characters are improperly formed, producing hollow
		images, the paper stock may be too slick. Try a different
		paper. See “Paper Type and Size” for faxing on page 1.17
		and “Selecting Print Media” for PC printing on page 4.1.
		• If characters are improperly formed, producing a wavy
		effect, the scanner unit may need service. Verify that it also
		occurs on a demo page.
		Press Demo ( ) on the front panel when the machine is
		ready.
		If you need service, contact a service representative.
