Title: Unfortunately, not TWAIN-compatible
Review: I make my living developing software for controlling scanners, and a very basic test shows that the FS-531 (as of December 6, 2004) has a pathetically broken TWAIN driver. I say "pathetically" because very basic software testing by Syscan would have revealed this bug before the FS-531 was released. If you only use this scanner from Photoshop or similar programs, it may well work - I can't say. If you attempt to use it with an automated scanning application, it will very likely crash (fatal error) - it will depend on the exact TWAIN features used by the application. This baffles me, since I would think that is exactly the type of application it would be *designed* to work with.
