Common causes

  • 1Incorrect network gateway/DNS settings.
  • 2Local IP address conflict within the office LAN.
  • 3Incompatible network protocols for scan-to-email or scan-to-folder.
  • 4Hardware communication failure at the Ethernet port.

Solutions

Diagnóstico rápido

This error manifests when the printer is unable to complete a handshake with the network gateway or workstation. If the printer panel shows an IP configuration error, the network infrastructure is likely to blame.

Solución paso a paso

  1. Check cabling and ensure no loose connections exist at the wall jack or switch.
  2. Set a static IP address on the printer’s control panel to prevent dynamic host conflict.
  3. Update printer firmware to the latest version to ensure compatibility with modern network security standards.
  4. Reboot the printer after applying settings to flush the internal network cache.

Prevención y mantenimiento

Use high-quality shielded Ethernet cables. Perform a periodic system reboot to refresh network connectivity modules. Keep software drivers updated across all network-connected workstations.

Cuándo llamar a un técnico

If settings verification and firmware updates fail to resolve the issue, the internal NIC (Network Interface Card) may be faulty.
