Common causes

  • 1Damaged Ethernet cable.
  • 2IP address conflict.
  • 3Router or switch port failure.
  • 4Incorrect gateway configuration.

Solutions

Diagnóstico rápido

If the Ethernet port lights are off, the connection is broken. If lights are on but the printer remains unreachable, it is likely a software conflict in the network gateway.

Solución paso a paso

  1. Swap the Ethernet cable to rule out damage.
  2. Power off/on both printer and switch.
  3. Access the menu to verify that the IP configuration is correct.
  4. Ensure no other device on the network shares the same static IP address.

Prevención y mantenimiento

Use Cat6 cabling and keep connections secure. Setting a static IP reservation in your DHCP server prevents common connectivity drops.

Cuándo llamar a un técnico

If the network cable is verified and internal settings are correct, but the port remains unresponsive, the internal network card may have failed.
