Loose toner
• Clean the inside of the machine. Contact a
service representative to clean the inside of
the machine. After cleaning the inside of the
machine, if you still have the same
problems, contact a service representative.
• Check the paper type and quality. (See
"Specifications on print media" on page 4.3.)
• Remove the toner cartridge, and then install
a new one. (See "Replacing the toner
cartridge" on page 6.5.)
• If the problem persists, the machine may
require repair. Contact a service
representative.
Character Voids
Character voids are white areas within parts of
characters that should be solid black:
• If you are using transparencies, try another
type of transparency. Because of the
composition of transparencies, some
character voids are normal.
• You may be printing on the wrong surface of
the paper. Remove the paper and turn it
around.
• The paper may not meet paper
specifications. (See "Specifications on print
media" on page 4.3.)
Horizontal stripes
If horizontally aligned black streaks or smears
appear:
• The toner cartridge may be installed
improperly. Remove the cartridge and
reinsert it.
• The toner cartridge may be defective.
Remove the toner cartridge and install a
new one. (See "Replacing the toner
cartridge" on page 6.5.)
• If the problem persists, the machine may
require repair. Contact a service
representative.
Curl
If the printed paper is curled or paper does not
feed into the machine:
• Turn the stack of paper over in the tray. Also
try rotating the paper 180° in the tray.
