Hi Scottb.
Thank you for using the forum.
I am not sure if you already searched the product knowledge base but I found a few solutions that may help. I didn't have all the specifics such as OS you are using or front end that you have but this may get you closer.
I selected the Fiery as your front end and found the following solutions that might help:
How To Set up the DocuColor (Version 1.1) With a Built-in Fiery Controller for Scan to File via FTP Using EFI Fiery WebTools

How To Access the Scan Services of the DocuSP Server From a Workstation Using a Microsoft Windows Operating System (OS)

If none of these help I would recommend that you try searching the product kb for a solution because there are several available. You may have a different front end and with the correct selection you may find the exact solution you need. If you don't find anything please contact support at 1-800-821-2797.
