"JAM INSIDE" error appears on the LCD.

If a paper jam occurs inside the printer, follow these steps:


  1. Turn off the printer's power switch and unplug the AC power cord.

    Turn Off Switch


  2. Fully open the top cover by lifting up on the handle (1).

    After you have just used the printer, some internal parts of the printer will be extremely hot. Wait at least 10 minutes for the printer to cool down before continuing to the next step.

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

    • Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
