Printing quality problems
211 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.
