Solutions

Quick Diagnosis

If your scanner reports U3, a paper is stuck along the feed path. If the motor sounds 'stressed', pull gently on the paper to verify where it is caught.

Step-by-Step Solution

  1. Safety stop: Stop scanning and release the ADF access hatch.
  2. Extraction: Locate the paper and pull it out carefully along the document path.
  3. Cleaning: Check for small paper bits left behind in the sensor area.
  4. Reset: Close the hatch, click it shut, and restart the scan app.

Prevention and Maintenance

Remove all metallic fasteners from documents. Cleaning rollers regularly ensures they maintain grip without causing multi-feeds or jams.

When to Call a Technician

If the scanner continuously reports U3 jams even without paper inside, the document sensors are malfunctioning.
