SEP blocking smb scan to folder

I'm running SEP 12.1 in unmanaged mode. I just set up a Ricoh MPC4000 copier and configured the scan to folder option. The scans kept failing. As soon as I disabled SEP it works fine. So, I know somewhere SEP is blocking it. I know I can add an allow rule but I'm sure one of the deny rules would override it. Aside from unchecking all the "block" rules, how can I allow this traffic through. Thanks for your help.
