After Windows update KB3161949 the scan to folder function on Ricoh copiers may fail.
The solution is to change the MFP default scan to folder port from 139 to 445.
To do so you need to connect via telnet to the MFP using the admin credentials and digit:
“smb client port” will show you the port that is currently using (should be 139).
“smb client port 445” to change the port.
“logout” to exit.
“yes” to confirm.
