Printing quality problems

If the inside of the machine is dirty or paper has been loaded improperly, there might be 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 101.) 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 "Print media specifications" on page 126.)

•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. (See "Cleaning the inside" on page 99.)

•The surface of the LSU part inside the machine may be dirty. (See "Cleaning the inside" on page 99.)

	CONDITION	SUGGESTED SOLUTIONS
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 "Print
		media specifications" on page 126.)
		• 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 Printing Preferences, click Paper tab, and set type to Thick. (See "Opening Printing Preferences" on page 47.)

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

White Spots	If white spots appear on the page:
	• The paper is too rough and a lot of dirt from a
	paper falls to the inner devices within the
	machine, so the transfer roller may be dirty.
	Clean the inside of your machine. (See
	"Cleaning the inside" on page 99.).
	• The paper path may need cleaning. (See
	"Cleaning the inside" on page 99.)
Vertical lines	If black vertical streaks appear on the page:
	• The surface (drum part) of the toner
	cartridge inside the machine has probably
	been scratched. Remove the toner cartridge
	and install a new one. (See "Replacing the
	toner cartridge" on page 119.)
	If white vertical streaks appear on the page:
	• The surface of the LSU part inside the
	machine may be dirty. (See "Cleaning the
	inside" on page 99.)
Color or Black	If the amount of background shading becomes
background	unacceptable:
	• Change to a lighter weight paper. (See "Print
	media specifications" on page 126.)
	• Check the environmental conditions: very
	dry conditions or a high level of humidity
	(higher than 80% RH) can increase the
	amount of background shading.
	• Remove the old toner cartridge and, install a
	new one. (See "Replacing the toner
	cartridge" on page 119.)
