Solutions

Diagnóstico rápido

The error light remains on regardless of actions. Check if the cover feels loose; if it doesn't click shut, the sensor won't release the lock.

Solución paso a paso

  1. Open the printer cover.
  2. Re-seat the paper roll to ensure no loose paper is blocking the latch.
  3. Clean the sensor area of any paper dust.
  4. Close the cover firmly until a clear click is heard.

Prevención y mantenimiento

Keep the paper path clear of dust. Regular air-cleaning of the internal sensors extends the life of the cover locking mechanism.

Cuándo llamar a un técnico

If the latch clicks correctly but the error E-05 persists, the sensor unit inside the chassis likely requires repair.
