As a followup to this thread. I finally got MotherF Ricoh to make a statement on this situation. By my own research also, this appears to be why the Ricoh fails. Pure SMB 3.0 will not work, what is needed is SMB 3.1.1. It appears that SMB 3.0 will send username/password in cleartext, then send the data encrypted. SMB 3.1.1 sends username/password in a SHA-512 hash (cyphertext), then sends data encrypted. Kyocera has this ability, Ricoh does not. MotherF Ricoh will come out with it first quarter of 2022.

SMB 3.1.1 was introduced with Windows 10 and Windows Server 2016.[41] This version supports AES-128 GCM encryption in addition to AES-128 CCM encryption added in SMB3, and implements pre-authentication integrity check using SHA-512 hash. SMB 3.1.1 also makes secure negotiation mandatory when connecting to clients using SMB 2.x and higher.
