Redistributing toner
When the toner cartridge is near the end of its life:
•
White streaks or light printing occurs and/or density variation side to side.
If this happens, you can temporarily improve 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.
Illustrations on this user’s guide may differ from your machine depending on its options or models. Check your machine type (see "Front view" on page 22).
•
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 area of the toner cartridge. Use the handle on the cartridge to avoid touching this area.
•
Do not use sharp objects such as a knife or scissors to open the toner cartridge package. They might scratch the drum of the cartridge.
•
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.
