Samsung SF-5100P manual Problem Possible cause and remedy

Problem	Possible cause and remedy
Black staining	• There is a paper quality problem. Use only paper that meets
	printer specifications.
	• A toner cartridge from another printer has been installed.
	Always use the same toner cartridge with the same printer.
	Using a cartridge that has already been used in another
	printer may not give satisfactory results.
Character voids	• The paper may be too dry. Try printing with a different batch
	of paper.
Background scatter	• 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 from the air.
	• Printing over uneven surfaces. If printing onto envelopes,
	change your printing layout to avoid printing over areas that
	have overlapping seams on the reverse side.
Missing characters	• 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 from the air.
Back of printout dirty	• The transfer roller may be dirty. Print a few blank pages to
	clean the transfer roller.
Incorrect fonts	• True type fonts may be disabled (Windows 3.x). Use the
	Fonts dialogue box in the Control Panel to enable True type
	fonts.
Faded graphics	• Toner may be low. Remove the toner cartridge and shake it
	gently to evenly distribute the toner. Then replace the toner
	cartridge. Have a spare toner cartridge in preparation for the
	toner running out.
