Common causes

  • 1Optical sensor blockage due to accumulated toner or paper dust.
  • 2Obstructed document path caused by staples or adhesive labels.
  • 3Intermittent internal data cable connection.
  • 4End-of-life condition of the optical sensor unit.

Solutions

Diagnóstico rápido

If your Fujitsu fi-4340C error E-06 appears, the scanner cannot confirm that a document has reached the internal tray. This is often caused by build-up that blocks the optical sensor. Check your device for debris immediately.

Solución paso a paso

  1. Disconnect the device from power for safety.
  2. Open the upper ADF unit and wipe the sensors with a lint-free cloth.
  3. Remove any paper scraps or debris caught in the transport path.
  4. Close the unit, reconnect the device, and perform a test scan.

Prevención y mantenimiento

Maintain the rollers with manufacturer-approved cleaning fluid every month. Keeping the scanner area away from direct paper dust sources will significantly extend the life of your internal sensors.

Cuándo llamar a un técnico

If you have performed a full cleaning and the error persists upon startup, the optical unit may be faulty. Contact professional service for component replacement.
