Replace the Waste Toner Box

Before starting the replacement procedure, see Related Information: Replace Supplies.

  1. Make sure the machine is turned on.
  2. Open the top cover until it locks in the open position.
    WARNING
    HOT SURFACE

    The machine's internal parts will be extremely hot. Wait for the machine to cool down before touching them.

  3. Remove all of the toner cartridge and drum unit assemblies.
    CAUTION

    We recommend placing the toner cartridge and drum unit assemblies on a clean, flat surface with disposable paper underneath it in case you accidentally spill or scatter toner.

    IMPORTANT

    To prevent damage to the machine from static electricity, DO NOT touch the electrodes shown in the illustration.

  4. Hold the green handle of the belt unit and lift the belt unit up, and then pull it out without letting it touch the machine.
  5. Remove the orange packing material and discard it.
    This step is only necessary when you are replacing the waste toner box for the first time, and is not required for the replacement waste toner box. The orange packing pieces are installed at the factory to protect your machine during shipment.
  6. Hold the green handle of the waste toner box and remove the waste toner box from the machine.
    DO NOT reuse the waste toner box.
  7. Unpack the new waste toner box and install the new waste toner box in the machine. Make sure the waste toner box is level and fits firmly into place.
  8. Reinsert the belt unit into the machine.
    NOTE
    To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
  9. Reinsert each toner cartridge and drum unit assembly into the machine. Make sure that you match the toner cartridge color to the same color label on the machine for all four toner cartridge and drum unit assemblies.
  10. Close the machine's top cover.
