Set-up Shared Fax Xerox Workcenter 5335

We currently have installed 2 Xerox Workcentre 5335 Copiers with the Fax module built in.  I have been tasked to find out how to set up a share printer that will only Fax.  This way out buisness can just select the shared printer to fax only.   I cannot find any documenttation if this is possible.  We can select the fax option from printer properties from the driver, but it would be ideal just to be able to select a printer and go.  Any help would be great!
