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

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