Problem: I bought my first Xerox DocuMate 510 in mid-2008. It works so well that when I wanted to replace an aging scanner for another office machine, I simply bought it again. I am running Win XP (paid extra not to get VISTA when I bought new machines) and find this scanner, combined with PaperPort 11, works beautifully. I do not use the "single touch" software that comes with it, having long since learned to use PaperPort for all scanning, so I cannot comment on its functionality. The machine itself does everything it saws, without error.
Solution: Positive
