Printing quality problems

If the inside of the machine is dirty or paper has been loaded improperly, you may notice a reduction in print quality. See the table below to clear the problem.

	CONDITION	SUGGESTED SOLUTIONS
Light or faded print If a vertical white streak or faded area appears
		on the page:

•The toner supply is low. You may be able to temporarily extend the toner cartridge

life. If this does not improve the print quality, install a new toner cartridge.

•The paper may not meet paper

specifications; for example, the paper may be too moist or rough. (See "Specification on print media" on page 33.)

•If the entire page is light, the print resolution setting is too low or the toner save mode is on. Adjust the print resolution and turn the toner save mode off. See the help screen of the printer driver and refer to Software section, respectively.

•A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. Contact a service representative.

•The surface of the LSU part inside the machine may be dirty. Clean the LSU, contact a service representative.

Toner specks	• The paper may not meet specifications; for
	example, the paper may be too moist or
	rough. (See "Specification on print
	media" on page 33.)
	• The transfer roller may be dirty. Clean the
	inside of your machine. Contact a service
	representative.
	• The paper path may need cleaning. Contact
	a service representative.
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 "Specification on print media" on
	page 33.)
	• The paper lot is bad. The manufacturing
	processes can cause some areas to reject
	toner. Try a different kind or brand of
	paper.

•Change the printer option and try again. Go to printer properties, click Paper tab, and set type to Thick Paper. Refer to the Software section for details.

•If these steps do not correct the problem, contact a service representative.
