Xerox Pro 580 manual AaBbCc, Problem, Possible Cause and Remedy

	Problem	Possible Cause and Remedy
Vertical repetitive		If marks repeatedly appear on the printed side of the
	defects	page at even intervals:
		• The laser printer cartridge may be damaged. Print a
	AaBbCc	cleaning sheet several times by cleaning the OPC drum
	AaBbCc	(see page 5.3). After the printout, if you still have the
	AaBbCc	same problems, install a new laser printer cartridge.
	AaBbCc	• Parts in the machine may have toner on them. If the
	AaBbCc	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.
	A	• The paper may be too damp. Try printing with a
		different 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	• If characters are improperly formed, producing hollow
characters	images, the paper stock may be too slick. See “Print
	Media” on page A.7 .
	• If characters are improperly formed, producing a wavy
	effect, the scanner unit may need service. Verify that it
	also occurs on a help list page.
	If you need service, contact a service
	representative.
