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.
