Aside exposure and AFE the backend probably uploads a scaling value for each image sensor element (white / dark shading etc.?) that should be pretty constant. (And no, I still have not read the genesys backend source to verify what it's doing, this is just from other educated experience.) I bet the Windows driver also does not re-calibrate every scan, at least the Mac driver for the Canon Lide 70 does only calibrate once after unpacking. Yours, -- Ren?
