Solutions

Diagnóstico rápido

Identify this error by the lack of response from the device in the PaperStream software. If the status indicator light flashes repeatedly without initiating the scan, a communication layer failure is present.

Solución paso a paso

  1. Unplug the scanner from the USB port.
  2. Restart your workstation to reset the USB bus.
  3. Reconnect the device to a rear-facing motherboard USB port.
  4. Update the TWAIN/ISIS driver if the error persists.

Prevención y mantenimiento

Keep the scan path clear of debris and avoid stretching the USB cable. A regular cleaning of the pick rollers every 5,000 sheets extends the device's service life.

Cuándo llamar a un técnico

If the device is not recognized by any computer with a known-good cable, the internal motherboard of the scanner may have failed.
