  • 1Internal network card communication failure.
  • 2IP address conflict in the subnet.
  • 3Hardware damage at the RJ-45 interface.
  • 4Firmware corruption affecting network protocols.

Solutions

Diagnóstico rápido

If the printer shows this code, try disconnecting the network cable. If the error disappears, your network environment (IP conflict, bad switch port) is the likely culprit.

Solución paso a paso

  1. Cabling: Replace the current Ethernet cable to rule out physical damage.
  2. Network Reset: Navigate to the Network settings on the printer and perform a reset to defaults.
  3. Firmware: Use a USB connection to update the firmware if the network interface is non-functional.
  4. Power cycle: Perform a full cold boot of the network switch and the printer.

Prevención y mantenimiento

Ensure high-quality shielded cabling. Regularly update firmware to prevent communication protocol mismatch in modern corporate environments.

Cuándo llamar a un técnico

If the error persists after a factory reset without a cable connected, the main system board may require component-level service.
