Solutions

Diagnóstico rápido

If the error code C001 is active, check the rear Ethernet LEDs. No activity suggests a cable or switch fault; constant activity without an IP suggests a network configuration conflict.

Solución paso a paso

  1. Reconnect the Ethernet cable to verify physical connection integrity.
  2. Check the printer settings to see if 'Network' is listed as 'Disconnected'.
  3. Assign a static IP address to the printer.
  4. Reboot your office router or switch.

Prevención y mantenimiento

Use category 6 network cables to prevent signal interference. If using wireless, ensure the signal strength is optimal to maintain a persistent connection.

Cuándo llamar a un técnico

If C001 persists after changing cables and manually setting an IP, the printer's onboard Network Interface Card (NIC) may need repair.
