Solutions

Diagnóstico rápido

If your computer lists the printer as 'Offline', this code usually points to a loose cable, an expired DHCP lease, or a faulty router port.

Solución paso a paso

  1. Check network cables: Ensure the Ethernet cable is securely connected at both the printer and the router/switch ends.
  2. Reboot networking hardware: Restart your router or switch to refresh DHCP address assignments.
  3. Reset network settings: Navigate to the printer control panel and perform a network setting reset to default values.

Prevención y mantenimiento

Use shielded Category 6 Ethernet cables for better signal integrity. Assigning a static IP is highly recommended to stabilize connections in business environments.

Cuándo llamar a un técnico

If the error persists after testing alternative network cables and refreshing the local router, there is a high possibility the internal network interface card is damaged.
