    Hello,

    I would like to enable the ultrasonic detection on multiple scans (CANON, FUJITSU, KODAK) with my application in C#.
    I saw more topics using parameters 0x8031 or 0x8032 but it does not work

    It depends on the manufacturer of the scanner. They use custom caps with values that change depending on the brand and/or model.

    I’ve solved it “sniffing” what the scanner TWAIN UI modifies using twirl.

    This is the tutorial I wrote for that:
