Solutions

Diagnóstico rápido

If the error appears suddenly, check the side and front doors. Sometimes a small plastic tab can get dislodged, preventing a full seal.

Solución paso a paso

  1. Open and close each access door for consumables.
  2. Inspect the small actuators (tabs) that trigger safety switches.
  3. Ensure no paper scraps are caught in the hinges.
  4. Power the printer off completely to restart the sensor detection cycle.

Prevención y mantenimiento

Avoid forcing doors when closing. Clean dust from the edges of the door frames, as accumulation can prevent the tab from making full contact with the sensor.

Cuándo llamar a un técnico

If the error persists after confirming all doors are well closed, the internal switch may be faulty and will require technical replacement.
