Solutions

Diagnóstico rápido

If your printer refuses to print and displays the err-02, the top lid is likely not fully latched. Check if both sides of the cover are properly engaged. If the cover seems locked but the error remains, the safety interlock switch may be obstructed.

Solución paso a paso

  1. Re-close the lid firmly, ensuring both latches engage with an audible click.
  2. Examine the latches and hinges for any broken plastic or debris.
  3. Clear the sensor area if you see any label scraps or dust blocking the safety switch.
  4. Restart the printer to clear the warning from the internal controller.

Prevención y mantenimiento

Avoid slamming the cover shut to protect the latch mechanisms. Use compressed air to clean the hinges and sensor area regularly, ensuring the safety switch remains functional.

Cuándo llamar a un técnico

If the cover is visibly locked and you have cleaned the sensor area but the err-02 still shows, the sensor switch may require professional replacement.
