Solutions

Diagnóstico rápido

If the software displays the U1-01 code, your PC isn't recognizing the scanner over the USB data bus. Verify if the scanner powers up normally. If the scanner remains inactive, the issue may be power-related rather than data-related. If it has power, focus your troubleshooting on the data cable and OS drivers.

Solución paso a paso

  1. Swap ports: Connect the USB cable to a different port, avoiding external USB hubs.
  2. Change cable: Replace the current USB cable with a new, high-quality shielded one.
  3. Driver management: Use Device Manager to uninstall the scanner, then restart to trigger redetection.
  4. Update software: Download and install the latest PaperStream IP driver from the Fujitsu official website.

Prevención y mantenimiento

Keep USB cables away from electromagnetic interference sources. Periodically update firmware and drivers to maintain compatibility with modern Windows versions. Using original or certified cables is highly recommended.

Cuándo llamar a un técnico

If you have tested the scanner on multiple computers with different cables and it still reports U1-01, the internal USB port on the mainboard may be damaged, requiring professional repair.
