According to the machine specifications at KonicaMinolta.com, the 7030 does not have a FAX option listed. So, is it a fax or not? Is there a phone cord plugged into it, or at least a place to plug a phone cord?
If it does have a FAX option on it, I don't beleive you would set up a fax service on Win2003. You would simply have another printer listed in your printer group called the Konica Fax (or something similar) and you would just print to that device rather than the printer. You would probably have to install the fax software that came with the printer to utilize it's capabilities. I may be wrong about this, but that's how it works for other all-in-one systems. The Windows Fax Service would be looking for a modem ON that computer.
