MSG_GETFIRSTFILE has nothing to do with a preview scan because it gets you the first file name in a folder see spec 1.9 page 174
to scan the first page and display is is ONE possibility to do a preview scan. maybe there are others but I couldn’t think of any
sorry, but I still have no idea what you mean with your event messages. the device will never ask to be calibrated becaust it is always calibrated with default settings.
if you want to check if there is any paper to be scanned than you have to swicht to automatic document feeder mode IF your scanner supports this, otherwise I don’t think that a scanner can tell if there is any paper to be scanned or not
