Horizontal stripes
Suggested solutions
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 printer may require repairing. Contact a service representative.
Curl
Suggested solutions
If the printed paper is curled or paper does not feed into the printer:
- 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.
- An unknown image repetitively appears on a few sheets
- Loose toner
- Light print or contamination occurs
Suggested solutions
- Your printer 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.
