Solutions

Diagnóstico rápido

The error ERR-H-02 appears if the printer detects that the printhead temperature is not being regulated correctly. If the printer boots and shuts down with this error, focus on the printhead connection.

Solución paso a paso

  1. Power off: Disconnect from the power source immediately.
  2. Visual inspection: Check the printhead surface for heavy residue or adhesive buildup.
  3. Cabling: Ensure the printhead connector is fully seated.
  4. Cleaning: Clean the thermal line with 99% isopropyl alcohol to ensure consistent heat transfer.

Prevención y mantenimiento

Perform regular cleaning with every ribbon change. Ensure the plant environment is clean and stable. Avoid using non-certified thermal ribbons that may increase the load on the printhead.

Cuándo llamar a un técnico

If the error persists after checking the connections, the printhead's internal thermistor has likely failed and the assembly needs replacement.
