Solutions

Diagnóstico rápido

If the error persists after checking the network cable status lights, it is almost certainly a conflict within the network settings. Try printing a network configuration sheet to verify the current IP status.

Solución paso a paso

  1. Ensure the Ethernet cable is not damaged.
  2. Swap the cable to a different port on the switch to rule out hardware failure.
  3. Power cycle the printer.
  4. If necessary, assign a static IP address via the web interface.
  5. Print a configuration page to confirm the IP change.

Prevención y mantenimiento

Assign a static IP to prevent addressing conflicts during router updates. Dust the connection ports periodically using compressed air.

Cuándo llamar a un técnico

If the network board fails to negotiate a link regardless of the cable or IP, the internal NIC might be faulty and require professional attention.
