Solutions

Diagnóstico rápido

The error E04 is a thermal protection alert. If the back of the machine feels very hot, the system has correctly identified that it needs a break to prevent component damage.

Solución paso a paso

  1. Immediate Shutdown: Turn off the power switch.
  2. Cooldown Phase: Leave the printer off for at least 20-30 minutes in a ventilated area.
  3. Clear Vents: Move the printer away from walls or tight corners to allow airflow.
  4. Restart: Turn the unit back on and resume your work slowly.

Prevención y mantenimiento

Try to print in smaller batches and keep the environment temperature within 10-32°C. Regular cleaning of internal vents helps sustain optimal cooling.

Cuándo llamar a un técnico

If the machine displays E04 immediately upon startup after a cold night, the temperature sensor may be malfunctioning.
