7.4 Solving Print Quality Problems

Dirt inside of the printer or improper paper loading may reduce print quality. See the table below to troubleshoot problems.

		The toner supply is low. You may be able to temporarily extend the toner cartridge life.
	AaBbCc	If this does not improve print quality, install a new toner cartridge.
		The paper may not meet paper specifications (for example, the paper is too moist or too
	AaBbCc
		rough).
	AaBbCc	A combination of faded or smeared defects may indicate that the printer needs cleaning.
