Solutions

Diagnóstico rápido

If you see C1 on your panel, inspect the scanner cover. If it looks closed but the error persists, it is a sensor detection failure.

Solución paso a paso

  1. Open the cover: Lift the lid fully.
  2. Clean area: Use a dry swab to clean the latch area.
  3. Inspect: Remove any stray paper scraps caught in the hinge.
  4. Close firmly: Press the lid down until it clicks securely.

Prevención y mantenimiento

Keep the latch mechanism free of dust. Do not slam the lid, as this can degrade the plastic parts over time.

Cuándo llamar a un técnico

If the cover is firmly closed and the error remains, the sensor switch may be faulty and needs hardware replacement.
