When the toner cartridge is near the end of its life:

White streaks and light printing occur.

Toner Low appears on the display.

The Status LED blinks red.

If this happens, you can temporarily reestablish print quality by redistributing the remaining toner in the cartridge. In some cases, white streaks or light printing will still occur even after you have redistributed the toner.

1Open the top cover.

2Pull the toner cartridge out.

Caution

• Avoid reaching too far into the printer. The fusing area may be hot.

To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Cover it with a piece of paper, if necessary.

Do not touch the green surface underside of the toner cartridge. Use the handle on the cartridge to avoid touching this area.

3Thoroughly shake the cartridge 5 or 6 times to distribute the toner evenly inside the cartridge.

Note

• If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.
