Printing quality problems

5. Troubleshooting
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.
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.
If the problem persists, the machine may require repairing. 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.
• Change the printer’s paper option and try again. Go to
Printing Preferences
, click the
Paper
tab, and set type to
Thin
.

Your machine is probably being used at an altitude of 1,000 m (3,281 ft) or above.
The high altitude may affect the print quality, such as loose toner or light imaging. Change the altitude setting for your machine (See "Altitude
adjustment" on page 106).
