Possible Explanation A
The Windows Firewall installed on your computer blocks the connection.
If no MFP server can be found, please make sure the Windows Firewall or any third party firewalls have been disabled or bypassed; then click the Search button to try again.
Possible Explanation B
The IP address of the computer is not within the same subnet as the MFP server.
Change the default IP address (192.168.0.10) of MFP server to match your network segment by Web management. If you have changed the default IP address but forgot it, please refer to the above section about the Load Default Setting to restore the default IP address of the MFP server.
