Solutions

Diagnóstico rápido

The error E-12 is indicated by flashing LEDs on the panel. If the machine fails to grab documents, it indicates a sensor trigger issue rather than a transport motor failure.

Solución paso a paso

  1. Restart unit: Turn off the device and power cycle it.
  2. Clean sensors: Wipe the glass paths with an alcohol-based wipe.
  3. Update drivers: Ensure your PC is using the latest PaperStream drivers.
  4. Check connection: Swap the USB cable to rule out signal degradation.

Prevención y mantenimiento

Keep the scan path clear of adhesive labels or dust. Periodic cleaning of the feed rollers is crucial for high-speed performance.

Cuándo llamar a un técnico

If the error persists after cleaning, there might be internal hardware damage, requiring service attention.
