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 61. 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 31.
		• 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.

AaBbCc	different brand of paper. See page 31.
	• The paper lot is bad. The manufacturing
AaBbCc	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.

White Spots White spots appear on the page:

•The paper is too rough and a lot of dirt from the

paper falls to the inner devices within the machine, which means the transfer belt may be dirty. Clean the inside of your machine. Contact a service representative.

• The paper path may need cleaning. Contact a service representative.

Vertical lines If black vertical streaks appear on the page:

•The drum inside the toner cartridge has probably been scratched. Remove the toner cartridge and install a new one. See page 61.

If white vertical streaks appear on the page:

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

Color or Black	If the amount of background shading becomes
background	unacceptable:

•Change to a lighter weight paper. See page 31.

•Check the machine’s environment: very dry (low humidity) or high humidity (higher than

80% RH) conditions can increase the amount of background shading.

•Remove the old toner cartridge and install a new one. See page 61.
