  • 4Loose sensor wire connection.

Solutions

Diagnóstico rápido

Error E-004 is usually caused by dust buildup. If the scanner fails to sense documents, the sensors need airflow.

Solución paso a paso

  1. Power off: Turn off the scanner for safety.
  2. Clean: Use compressed air to blow gently on the sensors.
  3. Inspect: Check for any remaining dust or lint blocking the sensor.
  4. Test: Turn on the unit and try a simple scan.

Prevención y mantenimiento

Keep the scanner covered when idle. Regularly clear interior dust with compressed air.

Cuándo llamar a un técnico

If sensor cleaning doesn't clear the E-004 error, the light sensor or the board might be internally faulty.
