So I finally figured it out because the manuals are so utterly disorganized. You don't need to download the WorkCentre software, which won't install unless you have an IIS installed apparently because all the error messages refer to it. Clearly this area has been long neglected by Xerox and potentially outsourced. You need to find the IP address of the printer because the startup software doesn't show you the quick option of clicking and getting there and the manual only provides this information deep into sepecific areas for setup regarding locating the IP address and using your browser to set up your printer (for items not accessible in the contro panel.) OK... that part solved.
But I'm still trying to figure out why scanning takes forever and there isn't a simple way to have the scanner scan documents using the ADF in Adobe Acrobat by choosing the automatic profiles, e.g. B&W, Color, Grayscale, as it does for the Documate 515. It scans very quickly and then you see a "Scan Progress" dialog box that takes well over a minute to complete even on 200 dpi black and white. It's preposterous.
-> The answer. You can't set the device to use a USB cable by default that I can see. So it always uses Wireless as the default option and it takes literally 10 times longer to use that option. The ONLY way to use the ADF is to (1) Choose your scan in Acrobat. (2) Set up the dialog box and, if you have a favorite setting, click "favorites" and select the favorite, click apply. (3) Click port and manually select "local" for the method of printing and close the box. Then start your scan. If you need to do this every time then you might as well shut down the offfice.
And while were at it, is there a way to set this printer to print using True Black and not Composite Black?
