Scan to usb service is missing

I have 2 5890's I am trying to get working for scan > usb. for the newer xerox machines, this is easy, but on these 2 I am runnning into problems.  machine # 1 first:

Scan to usb is enabled but there is no scan to usb service on the display . When I log in remotely to add the service there is none to add (there are plenty of services, just not scan to usb)

Is this like a weblet that can be downloaded and installed? If so where is it?

Thanks.
