Common causes

  • 1Dirty scanner glass: Dust or ink residue blocks light, fooling the sensor.
  • 2Worn rollers: Old rollers fail to pull the paper into the device.
  • 3Damaged documents: Items with glue or staples trigger safety stops.
  • 4Sensor blockage: Internal dust build-up confuses the document presence detection.

Solutions

Quick Diagnosis

The error AD typically flags an feeding inconsistency. Open the top cover; if there is debris or dust on the scan glass, it prevents the sensor from correctly detecting the page edges.

Step-by-step Solution

  1. Open cover: Push the release button to access the inner rollers.
  2. Clean glass and sensors: Wipe the image sensor glass thoroughly with a lint-free cloth.
  3. Check document path: Verify that no staples or small paper scraps are inside.
  4. Restart: Close the cover and power-cycle the scanner.

Prevention and Maintenance

Clean the scan glass every 500 scans to maintain sensor accuracy. Consistent maintenance prevents the build-up of toner dust which causes false error triggers.

When to Call a Technician

If the error persists after a thorough cleaning, the internal imaging sensor or the motor controller might be malfunctioning and needs repair.
