there is a new SPAR release firmware out containing SMB fixes
this will fix your issue
Make sure you have a domain set in the machine. Also 139 is for XP 445 Vista or later.
I tried port 445, no luck. I tried scanning to the root folder only, no luck. I've put the domain name in front of the user name, lpandt\Scan Docs, no luck. I created a new user and password, no change. All the other xerox machines (6) are scanning just fine with the credentials they are using for the 7845, just can't get the 7845 to work. The other machines are 7345 and 7120.

I'm having the same difficulty. When I loaded the smbclient patch, it wouldn't show on configuration page until I powered machine off and then on again. It still doesn't scan. Anyone with ideas?
