Hi! I have a CanoScan 8400F. As far as I can see from the specification pages of the 2 scanners on sane-project, they share exactly 1 chip and have a very similar second chip. However USB chip seems to be differnt. Also, from the specification on the canon homepage they seem similar.
As mentioned in an earlier post, I am not a programmer but willing to help in the development of the genesys-backend (to which the 8400F is supposed to be added). So perhaps, a very similar driver will drive both scanners, at least in the basic functionality. Perhaps I could help you? Greetinx, Wolfgang Sailer
