Replace WT Box

Follow the procedure below to replace the waste toner box.

Do NOT use flammable substances, any type of spray, or an organic solvent/ liquid that contains alcohol or ammonia to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.

  • DO NOT reuse the waste toner box.
  • DO NOT put the waste toner box into a fire. It could explode.
  • Be careful not to spill the toner. DO NOT inhale or allow it to get into your eyes.
  • Handle the waste toner box carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
  • Discard the used waste toner box according to local regulations, keeping it separate from domestic waste. If you have questions, call your local waste disposal office.
  1. Turn off the machine's power switch. Unplug the telephone line cord first (if applicable), disconnect all cables and then unplug the power cord from the AC power outlet (electrical socket).
     
  2. Fully open the top cover by lifting up on the handle (1).

    When the scanner is open you cannot open the top cover.

    • We recommend that you place the drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
