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.
Ensure that the paper is not wet, try paper from a fresh ream.

• If a vertical white streak or faded area appears on the page, the toner
supply is low. Install a new toner cartridge (see "Replacing the toner
cartridge" on page 57).
• 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 (see "Cleaning
the machine" on page 65).
• The surface of the LSU part inside the machine may be dirty. Clean the
inside of your machine (see "Cleaning the machine" on page 65). If these
steps do not correct the problem, contact a service representative.
The toner might not adhere properly to this type of paper.
• Change the printer option and try again. Go to Printing Preferences, click
the Paper tab, and set the paper type to Recycled (see "Opening printing
preferences" on page 41).
• The paper may not meet specifications; for example, the paper may be too
moist or rough.
