I hit the same problem with a Canon LiDE 110. I tried measuring the distortion by scanning a sheet of graph paper in various modes.
With sane 1.0.24 in 600dpi lineart and gray modes the scan is stretched vertically by about 30%. Color mode scans are actually also stretched at 600dpi, but much less noticeably by about 2%. The stretching is still visible though if you compare the scanned images side-by-side. With version 1.0.22 the lineart and gray scans are correct at 600dpi but the 2%-ish stretching is still present in 600dpi color mode. In case it helps I've put some of the scans up at http://www.chiark.greenend.org.uk/~akanaber/lide110/ Let me know if there's something else I can do that might help, Andrew M G Berberich wrote: > Hello, > > Canon LiDE 210 with sane-backends 1.0.24 (libsane:amd64 1.0.24-1.1+b1 > from debian testing) has problems with 600 dpi gray and lineart. > > In 600 dpi gray and lineart the scan is partial and aspect-ratio is > not correct.
