Common causes

  • 1Slippery rollers: Lack of grip causes motor response errors.
  • 2Internal obstruction: Debris inside the path.
  • 3Speed sensor fault: Controller detects incorrect rotation.
  • 4Insufficient power: Low-quality USB cable limits current.

Solutions

Quick Diagnosis

Error E-105 is identified when the scanner tries to pull paper but locks up abruptly. Check the feed tray for foreign objects or paper scraps that block roller movement.

Step-by-Step Solution

  1. Hardware Reset: Disconnect USB and power for 1 minute to reset the board.
  2. Deep Cleaning: Clean every feed roller with a microfiber cloth and distilled water.
  3. Feed Test: Insert one high-quality page to see if the error recurs.
  4. Connection Check: Connect to a primary USB port for sufficient power.

Prevention and Maintenance

Clean feed rollers every 500 scans to avoid dust accumulation, which is the primary cause of motor overloads. Store in a protective case when not in use.

When to Call a Technician

If the motor still sounds strained after cleaning or if E-105 appears without paper, the stepper motor might be damaged. Contact technical support.
