Hi, You can disable calibration without changing the code. You can do this in the frontend also (set SANE_DEBUG_GT68XX at least to 1 as explained in the man page).

A time of 20 seconds is normal. It should never take more than one minute. > In fact if I have the cover opened before scanimage start it takes 53 seconds I guess there is too much light from the outside (or the light changes too much) to get a stable calibration with the cover open. > If the cover is closed the scanimage takes 11 seconds to start This is ok.
