Cleaning the LEDs

Warning! Avoid touching the LEDs with anything other than a lint-free cloth. Fingerprints or scratches may cause other print quality problems.

LEDs

If you are experiencing print quality problems such as voids, light streaks, or light print, you may need to clean the LEDs inside the top cover.

To clean the LEDs:

1 Open the printer’s top cover.

2 Use a dry, lint-free cloth to clean all four LEDs.

3 Gently close the top cover until it clicks in place.

If print quality problems continue, you may need to replace photoconductors or toner cartridges. See page 109 for more information.
