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. See page 65. 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 page 33.
		• If the entire page is light, the print
		resolution setting is too low. Adjust the print
		resolution. See the help screen of the
		printer driver.
		• A combination of faded or smeared defects
		may indicate that the toner cartridge needs
		cleaning.
		• The surface of the LSU part inside the
		machine may be dirty. Clean the LSU,
		contact a service representative.
