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 “Paper
Specifications” on page D.6.
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 8.8.
• 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 over the stack of paper in the input tray. Also try
rotating the paper 180° in the input tray.
