Summary: The scanner arrived a few minutes ago, and when I opened the package I was shocked to discover it is a used scanner. All the cables are unwrapped, twist-ties loose in the bag, paper band warning of need to unwrap folded up and in bag, etc..
Excerpt: takes a while to warm up and the contrast is not very dark, I have to adjust the gamma and brightness to appropriate levels for good contrast, bit of a pain but easily done. Scans right up to the edge of a book page to within about a half inch totally flat with no distortion.
Summary: I bought this to scan some textbooks for OCR / voice conversion. It was fairly easy to setup, though the install disk wasn't quite automatic. I had to do a "custom" install to do each component Individually. I really like the simple one button scan next page.
Summary: Trying to use the OpticBook 3800 with the "beta" driver/app from Plustek for the Mac OS/X is really really painful. Even walking though things with the U.S. tech support got it sort of working but as others have mentioned, it crashes a lot.
Summary: I'm a university student and some of my teachers will assign a chapter out of an expensive text book and this scanner solved my problems. I can scan the chapter I need and return the book to the library without fear of a late fee. I have found this really great when I have todo papers.
Summary: This is a great scanner. It would have been 5 stars, except the software that comes with it is very clunky, and not written to Microsoft Windows standards. The "automatic" lens lock is sort of ok, if you place the scanner on a perfectly flat surface.
Summary: The scanner did install without any issues on Windows 7. I want to note that it requires a pretty long (~1min) warm-up period so the color temperature of the Cold Cathode lamps is controlled. Unfortunately they aren't using LEDs in this model.
