Solutions

Diagnóstico rápido

If the scanning job fails immediately after clicking start, the issue is at the server handshake. Verify other scan jobs are functional.

Solución paso a paso

  1. Verify permissions: Ensure the target folder has 'Write' permissions enabled for the assigned user.
  2. SMTP Check: Validate authentication credentials for email scanning.
  3. Firmware: Update the device to support modern SMB protocols.
  4. Reset destination: Re-create the scanning address in the printer directory.

Prevención y mantenimiento

Regularly check server security settings, as OS updates often lock down old sharing methods like SMBv1.

Cuándo llamar a un técnico

If the error persists after confirming server permissions, the printer's firmware logic may require a clean reinstallation by a technician.
