Fujitsu fi-7300NX Enterprise Error U2: Troubleshooting

The Fujitsu fi-7300NX Enterprise error U2 reports a document feed detection failure, typically occurring when feed rollers fail to pull a page correctly. This code appears when the paper sensor does not trigger after the intake mechanism activates. The issue is usually resolved with simple roller kit maintenance, typical for high-throughput enterprise devices.

Solutions

Diagnóstico rápido

The error U2 indicates that while the scanner senses documents in the tray, the rollers cannot move them past the intake point. Inspect for paper dust buildup or smooth/polished roller surfaces.

Solución paso a paso

  1. Power off and disconnect the scanner before starting any cleaning tasks.
  2. Open the ADF cover using the release lever at the top.
  3. Clean the feed rollers using F1 official cleaning fluid and a non-fibrous cloth.
  4. Check the separation pad to ensure it is correctly installed and not deformed.
  5. Close the unit securely and perform a test scan.

Prevención y mantenimiento

Paper dust buildup is the primary cause of roller failure. Perform weekly maintenance with the recommended kit. If rollers look glazed, replace the entire kit according to the manufacturer's cycle.

Cuándo llamar a un técnico

If the error U2 persists after thorough cleaning and kit replacement, the internal sensor or stepper motor may require professional diagnostic and repair.
