Solutions

Diagnóstico rápido

Check the LAN port indicators on the back of the printer. If there is no blinking activity, the network chip isn't receiving a handshake signal from the router, pinpointing the issue to cables or the port.

Solución paso a paso

  1. Replace the Ethernet cable with a confirmed working one.
  2. Power cycle both the router and the printer to refresh connection settings.
  3. Check network configuration in the printer settings; ensure IP settings match your network structure.
  4. Try a different LAN port on the switch to rule out hardware failure in the building wiring.

Prevención y mantenimiento

Use Cat6 Ethernet cables for stable signal transmission. Keep the device away from strong magnetic or electrical interference which could impact the LAN controller performance.

Cuándo llamar a un técnico

If all network troubleshooting steps fail, the onboard network interface card may be faulty and will need professional repair.
