  • 1Excessive print cycles without pause.
  • 2High print density (heat) settings.
  • 3Blocked rear airflow vents.
  • 4Residue on the thermal head sensor.

Solutions

Diagnóstico rápido

This error occurs during high-intensity print runs. If the thermal head feels hot, the integrated temperature sensor has correctly triggered a shutdown.

Solución paso a paso

  1. Cool down: Power off the printer for at least 15 minutes.
  2. Inspect: Check if there is debris blocking the printhead area.
  3. Ventilation: Ensure the device is in a well-ventilated space.
  4. Clean: Clean the printhead surface once cool.

Prevención y mantenimiento

Do not overload the printer with continuous print cycles without breaks. Adjust print heat settings to lower values if possible.

Cuándo llamar a un técnico

If the error persists after startup, the internal printhead thermistor may be faulty and requires a replacement.
