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 print cartridge life. See
			page 13.4. If this does not improve the print
			quality, install a new print cartridge.
		•	The paper may not meet paper specifications;
			for example, the paper is too moist or too
			rough. See page 5.8.
		•	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 page 2.4, respectively.
		•	A combination of faded or smeared defects
			may indicate that the print cartridge needs
			cleaning. See page 13.5.
		•	The surface of the LSU part inside the
			machine may be dirty. Clean the LSU. See
			page 13.2.
Toner specks		•	The paper may not meet specifications; for
			example, the paper is too moist or too rough.

			See page 5.8.
	AaBbCc	•	The transfer roller may be dirty. Clean the
	AaBbCc	•	inside of your machine. See page 13.2.
	AaBbCc		The paper path may need cleaning. See page
			13.2.

Dropouts		If faded areas, generally rounded, occur
		randomly on the page:
	AaBbCc	•	A single sheet of paper may be defective. Try
	AaBbCc	•	reprinting the job.
	AaBbCc		The moisture content of the paper is uneven
			or the paper has moist spots on its surface.
	AaBbCc
			Try a different brand of paper. See page 5.8.
	AaBbCc	•	The paper lot is bad. The manufacturing
			processes can cause some areas to reject
			toner. Try a different kind or brand of paper.
		•	If these steps do not correct the problem,
			contact a service representative.

	Condition		Suggested solutions
Vertical lines		If black vertical streaks appear on the page:
		•	The drum inside the print cartridge has
			probably been scratched. Remove the print
			cartridge and install a new one. See
			page 13.4.
		If white vertical streaks appear on the page:
		•	The surface of the LSU part inside the
			machine may be dirty. Clean the LSU. See
			page 13.2.
Gray background		If the amount of background shading becomes
		unacceptable:
		•	Change to a lighter weight paper. See
			page 5.8.
		•	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 print cartridge and install a
			new one. See page 13.4.

Toner smear	•	Clean the inside of the machine. See
		page 13.2.
	•	Check the paper type and quality. See
		page 5.8.

•Remove the print cartridge and install a new one. See page 13.4.

Vertical repetitive			If marks repeatedly appear on the printed side of
defects			the page at even intervals:
			•	The print cartridge may be damaged. If a
	A a B b C	c		repetitive mark occurs on the page, print a
	A a B b C			cleaning sheet several times to clean the
				cartridge; see page 13.5. After the printout, if
	A a B b C
				you still have the same problems, remove the
	A a B b C	c
				print cartridge and install a new one. See page
	A a B b C
				13.4.
			•	Parts of the machine may have toner on them.
				If the defects occur on the back of the page,
				the problem will likely correct itself after a few
				more pages.
			•	The fusing assembly may be damaged.
				Contact a service representative.
