Hi,
If you are able, you can try to build the pixma backend from branch
264-canon-pixma-mx492-adf-issues at the git repo.
You only really need the libsane-pixma* files to support your scanner.
If you are not sure how to do this, then let me know and I can help you out.
I just tried that branch code on my MX492 and it works fine. However
regular 1.1.1 is a bust on the ADF.
IIRC it was an alignment requirement that these particular machines are
more fussy about.
Cheers,
Ralph

Thanks for your time, Ralph!
The output of `scanimage -V` is:
scanimage (sane-backends) 1.1.1; backend version 1.1.1

I know that there are issues with this family of machines. I have
done
some work with a MX492 (that is not yet merged) and it has very
problematic ADF support.
I will drag out mine and try it with what you have above and see if I
get the same.
In the meantime, could you let us know the versions of your SANE
components?
scanimage -V
Cheers,
Ralph
