Utax DC 6240 SMB error 1105

[numarkDM1050]

By default, the file name is set to include the date and time.
I can't find the option to change the file name anywhere in the printer menus.

System Menu->Send Functions->File Name Entry would be the usual place but I'm still not sure what (US) model you are on, so you'll need to find an Operation Guide on your own.

I looked over the Wireshark again, and it has 3 tries which is typical for a Network scan attempt.

[numarkDM1050]

There is no such option in the web settings of the machine.
On the machine itself : Functions -> Enter file name entry ->
-> None
-> Data and time
-> Job No.
-> Job No. & data and time
-> Data and time & Job No.
I tried them all and the error is still the same.

Well congratulations, I'm stumped. The device simply stops before issuing the SMB_Create_Request and there is no indication of why in the trace that I can see.

You should attempt SMB scan to a Windows share (running wireshark) as a test on this machine. If it fails as well then the machine is suspect.

SMB steps in the trace:
SMB2 Negotiate - Attempted with success to dialect SMB 2.* (wildcard)
SMB2 Session Setup - Attempted with success NTLMSSP Auth for WORKGROUP\Ivo (user), GSS token issued
Tree Connect Request - Resolved to share \\172.18.4.44\123 with read write access. (123 sharename? Permitted but yuck)

To proceed, the machine must send the SMB_Create_Request to open the share and negotiate the file transfer...but it never does and instead (within milliseconds) sends a Tree Disconnect and Session logoff.

This indicates that the Send Operation is stopped by failure or intention in the machine programming at the point when it should create a file and send it. If it was an internal programming or hardware (memory) error I would expect some kind of System Error code.

Load known good firmware.
