    Hello,

    I have an issue where in some cases the scanner type does not get read properly. i.e. Sheet fed scanner versus flat bed scanner. Is there a way to check the scanner type? Is there a way to change the scanner type?

    From the FAQ [https://www.twain.org/faq.htm]:

    Question: Is it possible from a TWAIN application to know if a scanner is a flatbed scanner or not?

    Answer: Yes, it is. If CAP_FEEDERENABLED is not supported or it is but it cannot be set to true then it is safe to assume the scanner is a flatbed-only device (at least, this is the functionality that can be accessed from its TWAIN Data Source). If CAP_FEEDERENABLED is supported and can be set to true then the scanner is equipped with a feeder. If CAP_AUTOFEED is supported and can be set to true then the feeder is an automatic document feeder (ADF). If CAP_FEEDERENABLED is supported but the only supported value is true then the device would be a feeder-only scanner (or a similar device supporting only feeder-like operations).
