Xerox 3250 Condition Suggested solutions Vertical lines, Gray, Background, Toner smear, Defects

Condition		Suggested solutions
Vertical lines	If black vertical streaks appear on the page:
	•	The drum inside the print cartridge has
		probably been scratched. Install a new print
		cartridge. See page 8.3.
	If white vertical streaks appear on the page:
	•	The surface of the LSU part inside the printer
		may be dirty. Clean the LSU. See page 8.2.
Gray	If the amount of background shading becomes
background	unacceptable, the procedures below may fix the
	problem.
	•	Change to lighter weight paper. See page 5.3.
	•	Check the printer’s environment; low humidity
		(lower than 20% RH) 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 8.3.
Toner smear	•	Clean the inside of the printer. See page 8.1.
	•	Check the paper type and quality. See page
		5.2.
	•	Remove the print cartridge and install a new
		one. See page 8.3.

Vertical	If marks repeatedly appear on the printed side of
repetitive	the page at even intervals:
defects	•	The print cartridge may be damaged. If a
		repetitive mark occurs on the page, install a
		new print cartridge. See page 8.3.
	•	Parts of the printer 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.

Condition	Suggested solutions
Background	Background scatter results from bits of toner
scatter	distributed on the printed page.

• The paper may be too damp. Try printing with a different batch of paper. Do not open packages of paper until necessary so that the paper does not absorb too much moisture.

• If background scatter occurs on an envelope, change the printing layout to avoid printing over areas that have overlapping seams on the reverse side. Printing on seams can cause problems.

•If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application or via the printer properties window.

Misformed	• If characters are improperly formed and
characters	producing hollowed images, the paper stock
	may be too slick. Try a different paper. See
	page 5.3.

Page skew	•	Ensure that the paper is loaded properly.
	•	Check the paper type and quality. See page
		5.2.
	•	Ensure that the paper is loaded correctly and
		the adjustable guides are not too tight or too
		loose against the paper stack.
Curl or wave	•	Ensure that the paper is loaded properly.
	•	Check the paper type and quality. Both high
		temperature and humidity can cause paper
		curl. See page 5.2.
	•	Turn over the stack of paper in the tray. Also
		try rotating the paper 180° in the tray.
