Fujitsu ScanSnap S1300 error E-104: Sensor Fault

The Fujitsu ScanSnap S1300 error E-104 occurs when the optical paper presence sensor fails to detect document entry or exit correctly. This failure is usually caused by an accumulation of opaque residue, dust, or sticker adhesive that tricks the sensor, leading it to believe there is a permanent obstruction or no paper when one is inserted.

Common causes

  • 1Paper dust accumulation blocking the sensor's view.
  • 2Self-adhesive label residue in the detection area.
  • 3Optical calibration error due to direct ambient light.
  • 4Physical failure of the sensor's infrared transmitter or receiver.

Solutions

Diagnóstico rápido

The scanner is unresponsive or marks the error when trying to scan. Why does my Fujitsu ScanSnap S1300 show error E-104? The input sensor is blocked. Visually inspect the small slit where the sensor resides to ensure there are no stickers or thick dust obstructing it.

Solución paso a paso

  1. Power off the scanner and open the main cover completely.
  2. Inspect the sensor slot (usually at the ADF entrance).
  3. Use compressed air to eject any dust particles hidden in the sensor slot.
  4. Gently clean any visible residue near the scan area with a dry cloth.

Prevención y mantenimiento

Avoid scanning photos with adhesive or old documents that shed fragments. Perform internal cleaning with compressed air whenever the equipment has heavy usage in dusty environments.

Cuándo llamar a un técnico

If the error E-104 persists after cleaning the sensor area with air and a dry cloth, the sensor itself is likely faulty or the cable connecting it to the mainboard is damaged.

Frequently asked questions

This error means the document detection sensor is blocked or dirty, preventing the scanner from recognizing paper.

Cleaning is usually sufficient if the sensor is coated with toner or paper dust.

Do not apply liquid to sensors; use only compressed air or dry swabs.

Sometimes it is necessary to close the software and reset the USB connection.
