[sane-devel] Canon Pixma MG8250 - color scan, vertical misalignment

[Per Andersson]

I use a Canon Pixma MG8250 as home printer and scanner for my Gentoo Linux
system. I never got the printer to work correctly via USB using only
CUPS+Gutenprint drivers (no Canon proprietary software), so I switched to
connecting the device via Ethernet to my router (lpd protocol). This works
very well.

The scanner device (pixma) is detected by sane and I can read images using
scanimage.

When scanning color images in higher resolutions (>75 dpi) the colors are
misaligned in the output file, only in the vertical direction. I found a
bug report of a similar issue (concerning another Canon Pixma model) here:
https://alioth.debian.org/tracker/index.php?func=detail&aid=312022&group_id=30186&atid=410366


This seems to throw some light on the problem, but I don't dare open the
source files and hack them myself...
