Fujitsu fi-7900NX error E007: Sensor Failure

Fujitsu fi-7900NX error E007 refers to a multi-feed detection captured by ultrasonic sensors. Why is my Fujitsu fi-7900NX showing E007 error? Usually, the sensor detects two sheets passing through at once. This safeguards against missed information during critical document scans.

Common causes

  • 1Multi-feed: Two stuck sheets detected by ultrasound.
  • 2Dirty sensor: Lint or dust on the ultrasonic sensor.
  • 3Atypical document: Very thin paper causing false positives.
  • 4Separation roller wear: Roller no longer separates sheets properly.

Solutions

Diagnóstico rápido

If the scanning halts and E007 displays, the document might have stickers, or the sensor is dirty. Check if the documents are separated.

Solución paso a paso

  1. Remove the document that caused the halt.
  2. Clean the ultrasonic sensors with a dry cloth.
  3. Check if the paper is too thin for current settings.
  4. If the issue persists with standard paper, adjust detection sensitivity.

Prevención y mantenimiento

Clean the sensors whenever you perform roller maintenance. Avoid scanning documents with staples or clips that can confuse the detection system.

Cuándo llamar a un técnico

If the error appears consistently even with thick paper and clean sensors, the ultrasonic sensor unit might have internal failure.

Frequently asked questions

E007 is a multi-feed (double-sheet) detection error triggered by the ultrasonic sensors.

You can disable detection for envelopes or labels, but the error warns of potential data capture loss.

The official maintenance kit should be used per lifecycle, usually every 600,000 pages.

Very thin paper, wrinkled documents, or dust accumulation over internal ultrasonic sensors.
