Fix Konica Minolta bizhub C3320i Error C-D160 - Network

The C-D160 error code on the bizhub C3320i pertains to a Network Interface Controller (NIC) fault or communication authentication error. It typically occurs due to IP address conflicts, faulty cabling, or configuration mismatch. This prevents the MFP from communicating with the network infrastructure.

Common causes

  • 1IP address conflict within the local area network (duplicate IP).
  • 2Damaged RJ45 cable or corroded connector pins.
  • 3Router routing table overload preventing printer discovery.
  • 4Physical network chip failure due to power surges.

Solutions

Diagnóstico rápido

C-D160 appears when the machine fails to establish a stable handshake with your gateway or server. Inspect the LED indicators on the rear Ethernet port; no activity suggests a physical layer issue, while blinking or solid lights suggest software configuration errors.

Solución paso a paso

  1. Check cabling: Replace the existing network cable with a verified Cat6 cable.
  2. Cycle networking equipment: Restart your router or switch, then restart the printer to clear the IP lease.
  3. Set static IP: Access network settings and manually assign an unused IP address.
  4. Reset Network Settings: Use the control panel to perform a 'Reset Network Settings' to return to factory network defaults.

Prevención y mantenimiento

Reserve a static IP for the MFP in your router settings to avoid conflicts. Keep network cables neat and protected to prevent damage to the internal RJ45 port pins.

Cuándo llamar a un técnico

If all configuration resets fail and the printer does not obtain an IP address, the network component on the main board may be faulty and requires professional replacement.

    Ping the printer IP from a networked workstation to confirm communication.

Frequently asked questions

It is not critical for manual operation, but it disables all network functions including scan-to-folder and network printing.

Try connecting a different computer to the same network cable; if the computer connects successfully, the printer configuration is the likely cause.

The bizhub C3320i uses the TNP-81 toner series. Always use original cartridges to ensure optimal performance.

Using a static IP reservation in your router ensures the printer identity remains consistent on your network.
