Solutions

Diagnóstico rápido

If you see this error, printing remains functional, but scanning to network folders is interrupted. Check if there were any recent security updates on your Windows machine, as these frequently reset folder sharing permissions.

Solución paso a paso

  1. Verify path of the destination folder via the Web Interface (CWIS).
  2. Check credentials to ensure the printer has write access to the share.
  3. Switch to SMB v2/v3 if your environment no longer supports legacy protocols.
  4. Check the firewall to allow incoming scan traffic from the printer's IP.

Prevención y mantenimiento

Assign a static IP to your Xerox device to prevent connection drops. Regularly update your firmware to keep the network protocols compatible with the latest OS requirements.

Cuándo llamar a un técnico

If all network and share permissions are correct and the error persists, contact your network administrator to check for VLAN restrictions or network port blocking.
