Common causes

  • 1Excessive continuous printing cycle.
  • 2Darkness setting too high.
  • 3Inadequate ventilation around the printer.
  • 4Damaged printhead thermistor.

Solutions

Diagnóstico rápido

If the printer is physically hot to the touch, this is an expected safety shutdown. If the unit is cold and this occurs, the thermistor is likely failing.

Solución paso a paso

  1. Power down and let the device dissipate heat for 20 minutes.
  2. Reduce Darkness settings in your software/driver.
  3. Lower print speed to reduce load on the printhead.
  4. Clean the printhead with high-grade isopropyl alcohol.

Prevención y mantenimiento

Ensure the printer isn't enclosed in a non-ventilated cabinet. Adjust darkness levels to the minimum needed for a clean label scan.

Cuándo llamar a un técnico

If the error persists after power cycling and cooling, a technician may need to replace the printhead assembly due to a faulty thermal sensor.

Frequently asked questions

This error is triggered when the thermistor detects temperatures exceeding safety levels, aimed at preventing permanent heating element failure.

Yes. Continuing to print while overheating can destroy the printhead elements.

Low-melt thermal transfer ribbons allow you to lower the darkness settings, keeping the printhead cooler.

Keep the printer in a cool, ventilated area and balance speed vs darkness settings.
