Common causes

  • 1Accumulated paper dust blocking sensors.
  • 2Sticky tape residue on feed paths.
  • 3Normal wear and tear on pickup rollers.
  • 4Cover sensor mechanism misaligned.

Solutions

Diagnóstico rápido

If the sensors are covered in paper dust, the machine cannot trigger the scanning sequence. Check for any small scraps of paper, staples, or adhesive residue inside the ADF channel.

Solución paso a paso

  1. Unplug the power cable from the scanner.
  2. Open the upper cover and gently clean the optical sensors with a cotton swab and isopropyl alcohol.
  3. Ensure the rubber feed rollers are free of sticky residue.
  4. Close the lid properly until it clicks into place.

Prevención y mantenimiento

Clean the feed rollers and sensors after each batch of documents or at the end of every week. Avoid scanning thermal paper as it accelerates rubber roller wear.

Cuándo llamar a un técnico

If the error E-03 persists after a thorough cleaning, the internal sensor board may be misaligned or faulty, requiring professional service.
