Common causes

  • 1Permission Denied: Printer credentials lack write access on the target directory.
  • 2Firewall Blocking: Host machine firewall restricts incoming file transfers.
  • 3Incompatible SMB Protocol: Protocol version mismatch between printer and server.
  • 4DNS Error: The printer cannot translate the destination host name into an IP address.

Solutions

Diagnóstico rápido

If the scanning process starts but fails at the very end, it indicates that the machine is functioning properly but cannot save the file to the destination because of a network handshake or permission block.

Solución paso a paso

  1. Check the Remote UI to ensure the destination IP address or host name is correct.
  2. Confirm the destination user account has 'Write' permissions on the shared folder.
  3. Verify if your PC's firewall is allowing incoming connections from the printer's IP.
  4. Check the SMB protocol version compatibility if you recently updated your OS.

Prevención y mantenimiento

Maintain an updated list of destination IPs. Avoid using dynamic host names if they are prone to resolution errors in your environment.

Cuándo llamar a un técnico

If you cannot scan to any destination, even when using an IP-based destination and direct wired connection, there may be a defect in the network communication circuitry.
