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 "Specifications on print media" on page 4.2.)

•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 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.

	Condition		Suggested solutions
Dropouts		If faded areas, generally rounded, or broken
		texts or lines 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
			"Specifications on print media" on page 4.2.)
		•	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 paper
			type to Thick. Refer to the Software Section
			for details.
		•	Increase the level of the contrast of each
			color. To adjust the color contrast, click Start
			> Programs or All Programs > your printer
			driver name > Smart Panel and select
			Printer Setting > Graphic > Color and
			then click the Color Adjustment button.
			After Manual Color Adjustment window
			opens, move the scroll bar to the right
			direction. When finished, click Apply and
			then exit Smart Panel.
		•	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 toner cartridge has probably been
			scratched. Remove the toner cartridge and
			install a new one.

If white vertical streaks appear on the page:

• Clean the inside of the machine. Contact a service representative to clean the inside of the machine.
