Printing quality problems

If the inside of the machine is dirty or paper has been loaded improperly, there might be a reduction in print quality. See the table below to

clear the problem.

Condition Suggested solutions
Light or faded print • If a vertical white streak or faded area appears on the page, the toner supply is low. Install a new toner cartridge.
• The paper may not meet paper specifications; for example, the paper may be too moist or rough.
• If the entire page is light, the print resolution setting is too low or the toner save mode is on. Adjust the print
resolution and turn the toner save mode off. See the help screen of the printer driver.
• A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. Clean the
inside of your machine.
• The surface of the LSU part inside the machine may be dirty. Clean the inside of your machine. If these steps do
not correct the problem, contact a service representative.
