The Xerox WorkCentre 5330DN error 003-754 indicates an authentication error during an SMB scan-to-folder operation. The device fails to establish a secure connection with the target destination, likely due to outdated credentials, restricted folder permissions, or a mismatch in the SMB protocol version supported by the server.

Common causes

  • 1Incorrect network credentials for the SMB path.

Solutions

Diagnóstico rápido

Verify if your shared folder is reachable from another workstation using the same credentials. If it works on a computer but not the printer, the issue is definitely stored within the printer's repository profile.

Solución paso a paso

  1. Access the web interface using the printer's IP address.
  2. Navigate to 'Scan' and then 'Repository Settings'.
  3. Re-enter the username and password for the network scan destination.
  4. Ensure the server path is correctly formatted (e.g., \\server\share).
  5. Check if the SMB protocol is compatible with the server's security policy.

Prevención y mantenimiento

Keep printer firmware up to date to support newer network protocols. If using Windows Server, regularly audit user account permissions assigned to the scanning profile.

Cuándo llamar a un técnico

If the credentials are correct and you are certain the network is configured properly, there may be a defect in the network adapter or an underlying configuration conflict at the server level.
