Solutions

Quick Diagnosis

The U-01 error is the device's way of notifying that traction is uneven. If you feel a 'skipping' noise or paper stops halfway through, this is the cause of why my Fujitsu fi-7480 show error U-01 constantly. A visual inspection of the rollers is usually enough to confirm the diagnosis.

Step-by-Step Solution

  1. Open the scanner gate and check if the document is crumpled or blocked.
  2. Clean the traction rollers with a soft cloth and the agent recommended by Fujitsu.
  3. Ensure paper guides are correctly adjusted to the document width.
  4. Restart the device and perform a test scan with standard 80g sheets.

Prevention and Maintenance

Replace the Roller Kit when it reaches the service life recommended in the scanner software. Avoid digitizing documents with glue, as adhesive residue sticks to feed rollers rapidly.

When to Call a Technician

If the U-01 error continues appearing after cleaning the rollers and replacing the consumable kit, there may be an issue with the feed stepper motor that requires technical intervention.
