Solución paso a paso

  1. Power Cycle: Unplug the USB and power cables for 30 seconds to drain static charge.
  2. Switch Ports: Connect the device to a dedicated USB port on the back of your computer.
  3. Software Refresh: Close ScanSnap Manager from the system tray and relaunch the application.
  4. Cable Verification: Swap the existing USB cable with a verified working one to rule out wire breakage.

Prevención y mantenimiento

Clean the feed rollers every 1,000 scans to maintain smooth operation. Always use original ScanSnap consumables to ensure mechanical parts like rollers fit perfectly. Keep the scanner away from extreme temperature shifts and dusty environments to prevent internal sensor errors.

Cuándo llamar a un técnico
