Allan, Thanks very much - Following is a lot of "How to" questions? I can't try any of this now as I have to go to work - but I'll try these suggestions later tonight -
Just to clarify (here's my programming prowess coming to the fore!) - This is all done in terminal (not sane prefs?) -- How do I open this file : backend/genesys_devices.c ? once i see this file - it might make it all more clear for me.. How do I set GENESYS_FLAG_NO_CALIBRATION? How do I remove existing flags? and how do I rebuild the backend? once this is done, I can scan again from the TWAIN-SANE interface (without calibration)? as this code will affect the actual backend coding is that correct? ALso - if i screw it all up, can i re-insall and start again? Thanks a million for your help -- I'm never sure if these things work, but there's only one way to find out ..
