I think this is the interesting part of --help? Geometry: -l 0..200mm (in steps of 1) [0] Top-left x position of scan area. -t 0..200mm (in steps of 1) [0] Top-left y position of scan area. -x 0..200mm (in steps of 1) [80] Width of scan-area. -y 0..200mm (in steps of 1) [100]
So the values shown as default do not seem to be used. Your information has limited the problem enough that I don't mind debugging it from here.
