Redistributing toner cartridge
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.
1 Open the top cover.
2 Pull the toner cartridge out.
3 Thoroughly shake the cartridge 5 or 6 times to distribute the toner
evenly inside the cartridge.
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.
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.
