Solutions

Diagnóstico rápido

If the printer displays E002 upon startup, check if the rear exhaust area is extremely hot or cold. A grinding sound combined with this error points towards a mechanical fuser issue.

Solución paso a paso

  1. Power off the machine and unplug the cable.
  2. Allow the fuser unit to cool down for at least 20 minutes.
  3. Inspect the rear for any paper jams or foreign objects.
  4. Connect the printer directly to a wall outlet.
  5. Power the device on and listen for normal warm-up sounds.

Prevención y mantenimiento

Avoid printing on non-laser-compatible label sheets. These materials can easily jam or melt inside the fuser unit, causing temperature errors.

Cuándo llamar a un técnico

If the error persists despite letting the unit cool down, the fuser assembly needs professional repair or replacement.
