Common causes

  • 1Printing at maximum speeds for long durations.
  • 2Darkness setting higher than necessary.
  • 3Poor ventilation in the operating environment.
  • 4Residue trapping heat on the printhead surface.

Solutions

Diagnóstico rápido

If the printer is physically hot during the error, the protection system is working as intended. This usually results from extreme duty cycles in poorly ventilated industrial areas.

Solución paso a paso

  1. Pause: Switch off and allow time to cool.
  2. Adjust: Turn down 'Darkness' in settings.
  3. Speed: Lower print speed (ips).
  4. Maintain: Ensure the head is clean from dust.

Prevención y mantenimiento

Set the lowest possible 'Darkness' setting that still produces readable barcodes. Clean the printhead daily in high-volume environments.

Cuándo llamar a un técnico

If the error appears on a cold printer, the onboard thermistor is likely damaged and requires technician assistance.

    Adjust settings

    Lower the 'Darkness' value in the driver settings.

  3. 3

    Clean printhead

    Remove accumulated residue that traps heat.

Frequently asked questions

It happens due to prolonged high-speed printing or excessively high 'Darkness' settings, which push the thermal head temperature past safety limits.

Yes, repeated overheating can burn out printhead dots, causing permanent white lines on your labels.

Lower print speed and darkness settings; use compatible, certified thermal media to reduce the printhead load.

Ensure your industrial environment has sufficient airflow. Enclosed spaces accelerate heat buildup, triggering this alert.
