  • 2Darkness setting configured too high.
  • 3Dirty printhead increasing friction heat.
  • 4Poor ventilation or excessive ambient temperature.

Solutions

Diagnóstico rápido

If the printer stops and displays a flashing light while the printhead feels hot, the thermal protection has tripped. This prevents hardware degradation.

Solución paso a paso

  1. Power off the printer immediately and let it sit for at least 15 minutes.
  2. Disconnect the cable to ensure the system is fully discharged.
  3. Lower the print darkness settings in the printer driver or software.
  4. Clean the printhead thoroughly to reduce heat-generating friction.

Prevención y mantenimiento

Do not exceed the daily recommended duty cycle for this desktop model. Keep the area around the printer clear to allow for proper airflow.

Cuándo llamar a un técnico

If the error 3003 occurs even when the printer is completely cold, the internal thermal sensor may be faulty and need replacement.
