Samsung CLP-610 Condition Suggested solutions White Spots, Vertical lines, Color or Black, Skew

Condition		Suggested solutions
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.
Color or Black	If the amount of background shading becomes
background	unacceptable:
	•	Change to a lighter weight paper. (See
		"Specifications on print media" on page 4.2.)
	•	Check the environmental conditions: very
		dry conditions (low humidity) or a high level
		of humidity (higher than 80% RH) can
		increase the amount of background
		shading.
	•	Remove the old toner cartridge, and then
		install a new one. (See "Replacing the toner
		cartridge" on page 6.4.)
Toner smear	•	Clean the inside of the machine. Contact a
		service representative to clean the inside of
		the machine.
	•	Check the paper type and quality. (See
		"Specifications on print media" on page 4.2.)
	•	Remove the paper transfer belt, and then
		install a new one. (See "Replacing the toner
		cartridge" on page 6.4.)

Condition		Suggested solutions
Vertical repetitive	If marks repeatedly appear on the printed side
defects	of the page at even intervals:
	•	Clean the inside of the machine. Contact a
		service representative to clean the inside of
		the machine. After cleaning the inside of the
		machine, if you still have the same
		problems, install a new toner cartridge of the
		problem color. See "Replacing the toner
		cartridge" on page 6.4.
	•	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.
Background scatter	Background scatter results from bits of toner
	randomly 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 in printer properties.
Misformed	•	If characters are improperly formed and
characters		producing hollow images, the paper stock
		may be too slick. Try different paper. (See
		"Specifications on print media" on page 4.2.)
Page skew	•	Ensure that the paper is loaded properly.
	•	Check the paper type and quality. (See
		"Specifications on print media" on page 4.2.)
	•	Ensure that the paper or other material is
		loaded correctly and the guides are not too
		tight or too loose against the paper stack.
