    Hi,
    We got weird situation. To present a UI choice of available resolutions we read and show values for capability ICAP_XRESOLUTION.

    but Canon DR-3080C has this strange values:
    ICAP_XRESOLUTION:
    GET………….fix32 ENUM{ 100, 200 } Current: 200, Default: 200
    GETCURRENT……fix32 200
    GETDEFAULT……fix32 200
    SET………….200 ok
    SET………….240 ok
    SET………….300 ok

    so it reports that support only 100 and 200. but Twister tries 240 and 300 and both work. How does twister know that 240 and 300 should be checked. and why these work?

    do i miss something in specification? Any ideas?

    The choice of ICAP_XRESOLUTION of DR-3080C depends on ICAP_PIXELTYPE. In case of TWPT_BW and GRAY, the choice is 200, 240, and 300, and in case of TWPT_RGB, 100 and 200.

    Maybe Twister changes ICAP_PIXELTYPE from BW/GRAY to RGB (or from RGB to BW/GRAY) during the test.
