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.
