Fujitsu fi-7160 error U004: Multifeed Detection Fix

The Fujitsu fi-7160 error U004 is the common alert for multifeed detection. Using advanced ultrasonic sensors, the device determines if two pages are feeding at the same time. The resolution involves checking document condition and potentially adjusting the sensitivity settings within the software.

Common causes

  • 1Excessive electrostatic charge in documents.
  • 2Worn-out Pad Unit reducing sheet separation efficiency.
  • 3Ultrasonic sensitivity settings are too strict for specific paper weights.
  • 4Physical blockage in the sensor area.

Solutions

Diagnóstico rápido

The U004 code tells you that the scanner detected two sheets going through at once. If you're asking why does my Fujitsu fi-7160 show error U004?, it's likely a combination of document static or a worn-out separator pad.

Solución paso a paso

  1. Check papers: Remove any staples or paperclips.
  2. Calibrate sensor: Adjust ultrasonic sensitivity in the software if the paper is thin.
  3. Clean path: Clean the paper path of any accumulated dust.
  4. Retry: Align the stack cleanly and restart the scan.

Prevención y mantenimiento

Replace the Pad Unit at the recommended scan count. Keep the paper tray and feed guides free of dirt and debris.

Cuándo llamar a un técnico

If the scanner triggers U004 with high frequency even on clean, standard paper, the ultrasonic sensor might need professional alignment.

Frequently asked questions

The U004 error indicates a multifeed event where the sensor detects two sheets moving simultaneously.

Yes, through the software settings, but be careful as this risks missing data if sheets are actually stuck together.

The Pad Unit is crucial. A worn pad fails to provide the necessary separation force, causing multifeeds.

Keep the guides clean and follow the manufacturer's maintenance schedule for consumable replacements.
