Summary: We were using the earlier model of this DocuMate scanner and worked very well for our office needs. But as time goes by equipment will need to be replaced from over usage and due to failing parts. As of today our office staff appreciates the functions of this new scanner and according to them, works much more better than the previous model.
Summary: This is a very high-quality, bulletproof scanner for its time. It works fine on Windows XP with the included software, Nuance OmniPage and Nuance Paperport. On Windows 7 and higher, you should only install the Driver and the OneTouch software and either purchase the Nuance software or download ScanWiz. The older versions of OmniPage Pro and PaperPort will probably not work for you. If you're reading this in 2014 or later you are buying new/old stock.
Summary: I have a need to scan documents for my business. I was using a all-in-one HP device, but it was really inadequate for my needs and occasionally froze the computer during a scan. I decided to look for a new scanner and found the Xerox DocuMate 515. This scanner scans at a much faster rate, about 15 pages per minute. Combined with the fax unit on my Dell computer I am able to easily scan and fax as well. This was just the right combination for my business.
Summary: This scanner is a pretty good bang for your buck. On average it scans 12ppm, which is close to the 15ppm it advertises. Like other reviewers have said, it is a better idea to download the driver off the Xerox website than install the outdated driver from the CD. The Paperport and OmniPage software can be a bit confusing at first, but is easily learned.
