Scanning via USB on a Xerox 3635 is not supported. Here is the documentation:
http://www.support.xerox.com/support/phaser-3635mfp/support/enus.htmlYou may want to setup network scanning or Scan-to-PC.
If you need the Twain/WIA driver you can try installing the Windows Vista driver - It should work as needed. This scan is done over the network.
