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
		"Redistributing toner" on page 1). If this does
		not improve the print quality, install a new
		toner cartridge.
		• The paper may not meet paper specification;
		for example, the paper may be too moist or
		rough (See "Selecting print media" on page 2).
		• 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.
		• A combination of faded or smeared defects
		may indicate that the toner cartridge needs
		cleaning.
		• The surface of the Laser Scanning Unit (LSU)
		part inside the machine may be dirty. Clean
		the LSU, contact a service representative.
