Quick Diagnosis

The 400-01 error appears on the panel during scan-to-folder or network print tasks. Test by 'pinging' the printer's IP address from a workstation to see if the device is reachable.

Step-by-Step Solution

  1. Inspect the Ethernet cable for signs of wear or damage.
  2. Access the printer’s web interface to verify no IP conflicts exist on your subnet.
  3. Restart the printer and the network switch to clear cache.
  4. Set a static IP address instead of using DHCP to maintain a permanent connection.

Prevention and Maintenance

Reserve static IP addresses for your office printers within the DHCP server. Periodically update the network controller firmware to ensure optimal performance.
