Printing quality problems
285 6. Troubleshooting
Loose toner • Clean the inside of the machine (see "Cleaning the machine" on page 79).
• Check the paper type and quality.
• Remove the toner cartridge and then, install a new one (see "Replacing the toner cartridge" on page 75).
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.
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 75).
If the problem persists, the machine may require repairing. Contact a service representative.
