Thanks Joe -
I did install the scan driver "Windows USB Scan Driver, from Xerox's driver website, and get the scan feature working for my Xerox WorkCentre 6605 Multifunction Printer. But, instead replacing the Xerox Global Print Driver PS, under Devices and Printers, selecting the Printer (Xerox WorkCentre 6605), and under Advanced, clicking New Driver. I went to Device Manager/Imaging Devices, righ-clicked on the Printer, Xerox WC 6605 (WUA-USB), Browsed to the location of the downloaded scan driver and installed the scan driver that way. I also then went to Start on the desktop, All Programs, Xerox Office Printing, clicked on Xerox WorkCentre 6605, clicked the Express Scan Manager and set the folder for where scans go.
Thanks again Joe. I am able to scan & print now !
