you can get lots of info from their website... http://graphics.kodak.com/docimaging/US/en/Products/Document_Scanners/Departmental/i260_Scanner/index.htm > > The CompressionType byte on SetWindow command is set to 0, I think that > means uncompressed. > > I'd find a couple of bytes with names like scan_method and scan_mode on > SetConfig command.
