You are trying to scan to the IP of 10.0.0.20 on port 139, I would suggest 445
Assuming the root share that can be seen on the SMB server at 10.0.0.20 is Xerox then the share name you have is correct.
Document path is not OK at all, it is meant to be the file path after the Xerox folder, and you started it with \\ which means SMB, and then you put what is clearly a hostname and not a folder and followed it up with a completely different folder than you used in the Share name, so in effect, you told the printer to do:
SMB connect to 10.0.0.20
go into folder Xerox
Somehow initiate a completely different SMB connect to a PC with hostname DEESKTOP-STDN3JS
then go into another folder called Scanuri Xerox
To simplify, on the PC hold down the Windows key and tap the letter R
in the run command, type in "\\10.0.0.20" without the quotes
once it opens, whatever folder you see is what goes into Share
If you go into it and see another folder you want to go into you put it in Document path (Do not use any slashes)
I can't troubleshoot the login name , but if it is Windows 8 or higher it will need to be an email address or
DESKTOP-STDN3JS\Tehnic-PC according to what you have there now
