4.2.4 Solving Print Quality Problems

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

troubleshoot problems.

1) Light or faded print

1. 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.

2. The paper may not meet

paper specifications

3. A combination of

faded or smeared defects may

indicate that the printer

needs cleaning

Check the paper type and quality

Check the inside for the printer.
