    WARNING
    HOT SURFACE

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

  3. Remove the toner cartridge and drum unit assembly for the color shown on the LCD.
    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.

    The shape of the toner cartridge will vary depending on your country and region.

    Make sure you put the toner cartridge in correctly or it may separate from the drum unit.

    Be sure to return the green tab to the Home position (). The arrow on the tab must be aligned with the arrow on the drum unit. If it is not, printed pages may have a vertical stripe.
