If the software installs, and runs, but can't communicate, yet the PC can communicate by every other testable means, I would look at disabling the firewalls. Must be that doing the block since we know port 80/443 (CWIS) and port 515 and 9100 (prints) are working.
The network scan software not found printer on the lan network; does not work the automatic scanning and even the ip manual entry.
No error message.
The connection to the webserver of the printer with the IP adress and the browser works.
The other network PC with Windows 7 e netscan software works.
"not working" is not enough information.
Isn't on the PC?
Runs but doesn't connect?
Error message at the moment it "doesn't work"?
Have you simply removed it, rebooted the PC and reinstalled it?
It's been 7 years since any drivers were developed for this printer, so it is safe to say it is no longer supported or developed for, if Windows 10 has an update that thoroughly kills it's software you may need to roll back to Version 1511 of Windows 10 (Pre Version 1607 "Anniversary" edition), Upgrade the printer or scan to a shared drive on the Windows 7 PC, and map the share to the Windows 10 PC so both PC's can grab the scans.
After installation windows 10 update july 2016 network scanner functionality Xerox 3300MFP not working.
I use xerox network scan manager software.
I regularly print.
With my browser i connect to the printer webserver with this pc and it works.
In the same lan network another pc with windows 7 works very well with xerox network scan manager.
