You need to post details.
What are the settings in your SMB share, or FTP settings that you set up on the Windows 10 PC?
You would also really help out if you went into CWIS and took a screenshot of the Addressbook entry so we can see how you formatted the scan settings in there.
Due to Windows 10 using SMBv3, you would be more likely by far to get FTP working.
If you are running the Scan Driver, Does Windows show it? Have you set it by IP or the USB?
