    Hi, I have a question for the experts.

    Im using an Avision Scanner, model AV220C2 that support duplex.

    I have set it via the twain specification, successfully.
    My xfermech is the default, native.

    Only one question

    When i scan a page, the call return to me the DIB to only one face of my page. how can i get the two face?

    Hope to be clear.

    The second (back) image transfer is separate from the first (front) transfer. It’s handled as though the scan was two single-sided pages using document feeder. See “Transfer of Multiple Images” in the TWAIN specification 1.9 (page 4-90) for details.

    We’re here to help if you get stuck again.
