Solutions

Diagnóstico rápido

The error appears when the thermal print head is not detected as being closed. If you check the physical latch and it feels loose, the sensor is correctly reporting the state.

Solución paso a paso

  1. Lift the printer cover.
  2. Fully raise the print head latch.
  3. Firmly press the latch down until you hear a clear, audible click.
  4. Check the display to ensure the error clears.

Prevención y mantenimiento

Do not overload your media path, as excessive thickness can push against the head and create latch pressure. Clean the internal latch sensors regularly.

Cuándo llamar a un técnico

If the latch clicks correctly but the error remains, the physical switch inside the unit may need expert replacement.
