Scanning problems
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 "Specification on print
Horizontal stripes
If horizontally aligned black streaks or smears
appear:
• The imaging unit may be installed
improperly. Remove the cartridge and
reinsert it.
• The imaging unit may be defective.
Remove the toner cartridge and install a
new one. (See "Replacing the toner
• If the problem persists, the machine may
require repair. Contact a service
representative.

feed into the machine:
• Turn the stack of paper over in the tray.

set type to Thin Paper. Refer to the
