Product Makes Noise, But Nothing Copies
If your product makes a noise, but nothing copies, try these solutions:
• Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if
necessary.
• If the nozzle check page does not print, but the product's power is on, make sure your product
software is installed correctly.
• Make sure your product is level (not tilted).

Copies Have Incorrect or Faint Colors
If your copies have incorrect, uneven, smeared, or faint colors, try these solutions:
• Run a print head nozzle check to see if any of the nozzles are clogged. Then clean the print head, if
necessary.
• Do not press too hard on the original when you copy from the scanner glass.
• Clean the scanner glass with a soft, dry, lint-free cloth or use a small amount of glass cleaner on the
cloth, if necessary. Paper towels are not recommended.
Caution: Do not spray glass cleaner directly on the scanner glass.
• Clean the ADF.
• Wipe any dirt or dust off of your originals.
• If the colors are smeared, try lowering the copy density setting on the LCD screen.
• Make sure your paper is not curled.
• When vertical banding appears or the paper is smeared, clean the paper path.
