Solutions

Quick Diagnosis

If you try to enter the printer's settings via IP from your browser and get this error, the printer isn't responding on the local network. Check if other devices can see it on the network segment.

Step-by-step Solution

  1. Restart: Turn off the unit and restart the router/switch to clear the IP address table.
  2. Check IP: Access the menu on the printer's LCD screen and confirm the IP is fixed (static) and not in conflict with another device.
  3. Connection: Check the RJ45 cable. If the port LED isn't blinking, replace the network cable with a new one.

Prevention and Maintenance

Assign a reserved static IP in your router for the printer. This prevents the router from reassigning a different IP after power cycles, avoiding connection losses.

When to Call a Technician

If after setting a static IP and testing with another cable the LAN port remains dead, the main network board might be damaged.
