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
	extend the toner cartridge life. See “Redistributing Toner”
	on page 4.3. If this does not improve the print quality,
	install a new toner cartridge.
	• The paper may not meet paper specifications (for
	example, the paper is too moist or too rough). See “Paper
	Specifications” on page 6.3.
	• If the entire page is light, the print resolution setting is too
	light or the Toner Save mode is on. Adjust the print
	resolution and the Toner Save mode in the printer
	properties. For details, see Software User’s Guide.

•A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. See “Cleaning the Inside” on page 4.6.

•The surface of the LSU part inside the machine may be dirty. Clean the LSU. See “Cleaning the Inside” on page 4.6. Contact a service representative.

Toner specs	• The paper may not meet specifications (for example, the
	paper is too moist or too rough). See “Paper
	Specifications” on page 6.3.
	• The transfer roller may be dirty. See “Cleaning the Inside”
	on page 4.6.
	• The paper path may need cleaning. See “Cleaning the
	Inside” on page 4.6.
Dropouts	If faded areas, generally rounded, occur randomly on the
	page:
	• A single sheet of paper may be defective. Try reprinting
	the job.
	• The moisture content of the paper is uneven or the paper
	has moist spots on its surface. Try a different brand of
	paper. See “Paper Specifications” on page 6.3.
	• The paper lot is bad. The manufacturing processes can
	cause 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.
