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.
Light or faded print
If a vertical white streak or faded area appears on the page:
The toner supply is low. You may be able to temporarily extend the toner cartridge life.
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
rough).
A combination of faded or smeared defects may indicate that the printer needs cleaning.
