I've captured a log of a Windows scan (100dpi, colour) with a Canon Lide 80. It is available at http://plam.csail.mit.edu/~plam/tmp/lide80.windows.log.gz I've modified the sane genesys backend, copying the lide50 entry to a lide80 entry, but it doesn't work: http://plam.csail.mit.edu/~plam/tmp/lide80.log pat
