This error occurs when the printer loses its handshake with the local network. Common causes include router reboots, password updates, or IP range conflicts.

Step-by-step Solution

Cycle power on both devices.
Verify Wi-Fi signal quality in the printer menu.
Update network credentials if the router password changed.
Use Ethernet as a fallback test.

Prevention and Maintenance

Assigning a static IP address is the best preventative measure against dynamic IP conflicts in local environments.

When to Call a Technician

If hardwired Ethernet also fails to connect, the NIC card may be faulty.
