You can clean the cartridge up to three times. Each successive cleaning is more thorough and uses more ink.

If you complete all three levels of cleaning using this procedure and you still notice white streaks or missing colors on the test page, you may need to clean the print cartridge copper-colored contacts. For more information, see the following section.

Note If the cartridge or printer has been recently dropped, you may also see white streaks or missing colors in your prints. This problem is temporary and clears up within 24 hours.

Cleaning the print cartridge contacts

If you use the printer in a dusty environment, debris may accumulate on the copper- colored contacts and cause printing problems.

To clean the print cartridge contacts:

1Gather the following items to clean the contacts:

–Distilled water (tap water may contain contaminants that can damage the print cartridge)

–Cotton swabs or other soft, lint-free material that will not stick to the print cartridge

2Open the print cartridge door.

3Remove the print cartridge and place it on a piece of paper with the ink nozzle plate facing up. Be careful not to touch the copper-colored contacts or the ink nozzle plate with your fingers.

Caution Do not leave the print cartridge outside the printer for more than 30 minutes. Ink nozzles exposed to the air longer than this may dry out and cause printing problems.

4Lightly moisten a cotton swab with distilled water and squeeze any excess water from the swab.

5Gently wipe the copper-colored contacts with the cotton swab.

Caution Do not touch the ink nozzle. Touching the ink nozzle will result in clogs, ink failure, and bad electrical connections.
