Common causes

  • 1Data interface timeout during communication.
  • 2Damaged USB/SCSI cable.
  • 3Corrupted or outdated system drivers.
  • 4Motor overload due to feed path resistance.

Solutions

Quick Diagnosis

If the error code displays on the scanner panel immediately upon boot, check for internal faults. If it occurs after the scanner is active, focus on the USB or SCSI cable connection.

Step-by-Step Solution

  1. Power Cycle: Shut down and disconnect all cables.
  2. Check Cables: Ensure the data cable is firmly seated in the port.
  3. Driver Reset: Reinstall or update the PaperStream IP drivers on your workstation.
  4. Initialization: Power the device back on and confirm the connection status in your scanning software.

Prevention and Maintenance

Keep the paper path clean from debris. Worn rollers can cause intermittent errors that may be reported incorrectly by the system firmware.

When to Call a Technician

If the communication error persists despite trying different cables and PC ports, the internal interface card might be failing.
