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. Vertically only about ? of the area is scanned and then scaled to the area, horizontally all is fine. (So probably the driver sets the wrong scanline-skip (to small)). This worked in older versions, at least 1.0.22. 600 dpi Color-scanning works fine, so do preview, 300dpi and 1200 dpi in all modes. 2400 dpi and 4800 dpi do not work at all, but never did.
