Solving Print Quality Problems

Dirt inside of the printer or improper paper loading may reduce the print quality. See the table below for troubleshooting.

Problem	Solution
Light or faded	If a vertical white streak or faded area appears on the page:
print	• The toner supply is low. You may be able to temporarily
AaBbCc	extend the toner cartridge life. See “Redistributing the Toner”
	on page 6.5. If this does not improve the print quality, install a
AaBbCc	new toner cartridge of the faded color.
	• The paper may not meet paper specifications (for example,
AaBbCc
	the paper is too moist or too rough). See “Paper
AaBbCc	Specifications” on page G.4.
AaBbCc	• A combination of faded or smeared defects may indicate that
	the toner cartridge needs cleaning. See page 6.31.
	• The surface of the LSU may be dirty. Clean the LSU. See
	page 6.30.
Toner specs	• The paper may not meet the specifications (for example, the
AaBbCc	paper is too moist or too rough). See “Paper Specifications” on
	page G.4.
AaBbCc	• The transfer roller or the paper path may be dirty. See
AaBbCc	“Cleaning the Inside of the Printer” on page 6.31.

Dropouts	If generally rounded, faded areas occur randomly on the page:
AaBbCc	• A single sheet of paper may be defective. Try reprinting the
	job.
AaBbCc	• The moisture content of the paper is uneven or the paper has
AaBbCc	moist spots on its surface. Try a different brand of paper. See
	“Paper Specifications” on page G.4.
AaBbCc	• The paper lot is bad. The manufacturing process can cause
AaBbCc	some areas to reject toner. Try a different kind or brand of
	paper.
	• The toner cartridge may be defective. See “Vertical repetitive
	defects” on the next page.
	• If these steps do not correct the problems, contact a service
	representative.
