It would be nice if it could , simply so you would be able to back up any fax in or out, but....
Any random could enable said feature, and you could go to the device to send or receive a fax, and all would appear to be correct, but that random would have a copy of your fax. Now place that fax machine in a Law Office, or Hospital, or Government office.
I don't believe Xerox would take the chance simply for that reason alone, but I may just be paranoid.
