	Condition		Suggested solutions
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
			13.5.
		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.
Colour or Black		If the amount of background shading becomes
background		unacceptable:
		•	Change to a lighter weight paper. See page
			5.2.
		•	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 13.5.

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

	Condition		Suggested solutions
		Background scatter results from bits of toner
		randomly distributed on the printed page.
Background		•	The paper may be too damp. Try printing
			with a different batch of paper. Do not open
scatter
			packages of paper until necessary so that
			the paper does not absorb too much
	A
			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 the printer properties.
Misformed		•	If characters are improperly formed and
characters			producing hollow images, the paper stock
			may be too slick. Try a different paper. See
			page 5.2.
		•	If characters are improperly formed and
			producing a wavy effect, the scanner unit
			may need service. For service, contact a
			service representative.

				If marks repeatedly appear on the printed side
				of the page at even intervals:
Vertical repetitive				•	The toner cartridge may be damaged. If a
					repetitive mark occurs on the page, print a
