Note:
The MFP Server IP Address should be in the same network
segment with the connected computer. If the network settings are
incorrect, a message will be prompted to remind you after you click
"Next". Please make sure that you have set the right settings
before going to the next step. If you don't want to set it now, please
click "Cancel" to finish the installation. You can then use the
"Server Manager" utility to configure the MFP Server.
