<p>Hi Jean,</p>
<p>If you like, you can install SANE from the git repository as
described in INSTALL.linux (<a class="moz-txt-link-freetext" href="http://sane-project.org/docs.html">http://sane-project.org/docs.html</a>) to
find the problem in the source code.</p>
<p>Most interesting are the commits from the master branch
containing changes for files starting with pixma after 27.05.2017.
Usually these commits come from Olaf Meeuwissen or from me. Please
checkout these commits, compile and test them. Easy to use git
frontends are git-gui, gitk or gitg. But you must checkout a
commit with its sha1-id from the command line (the 1st 6 to 7
characters of the sha1-id are enough to identify the commit),
e.g.: </p>
<p>$ git checkout c2594e<br>
Note: checking out 'c2594e'.<br>
<br>
You are in 'detached HEAD' state. You can look around, make
experimental<br>
changes and commit them, and you can discard any commits you make
in this<br>
state without impacting any branches by performing another
checkout.<br>
<br>
If you want to create a new branch to retain commits you create,
you may<br>
do so (now or later) by using -b with the checkout command again.
Example:<br>
<br>
git checkout -b <new-branch-name><br>
<br>
HEAD ist jetzt bei c2594e9... Revert "pixma_imageclass.c: MF240
Series supports only 300dpi for adf scans"<br>
<br>
</p>
<p>Please report the branch which 1st produces the problems you've
reported before.</p>
<p>Otherwise we must wait some weeks finding the problem commit.<br>
</p>
<p>Hope this helps.</p>
<p>Cheers,<br>
Rolf<br>
</p>

<div>Hi Rolf, </div>
<div><br>
</div>
<div>First, thank you for looking into this.</div>
<div>Second, there is no rush, as I have a workaround reverting
to 1.0.25,</div>
<div><br>
</div>
<div><br>
</div>
<div>I've tried with sane-release ppa, </div>
<div>
<div>scanimage (sane-backends) 1.0.27git; backend version
1.0.27</div>
</div>
<div>and it works fine</div>
<div><br>
</div>
<div>same with sane-test, which is ok,</div>
<div><br>
</div>
<div>I've reverted to sane-git, and it fails again.</div>
<div><br>
</div>
<div>Let me know if you need more info, </div>

<br>
Please try my other ppa's (SANE Release and SANE Test) with
older<br>
versions of SANE: <a
href="https://launchpad.net/%7Erolfbensch"
rel="noreferrer" target="_blank" moz-do-not-send="true">https://launchpad.net/~<wbr>rolfbensch</a>
and report the<br>
results. Then I'll have an idea where to search for the
issue you reported.<br>
<br>
Please be patient. I'm on the move until end of August and I
have less<br>
time to work on SANE.<br>
<br>
Hope this helps.<br>
<br>
Cheers,<br>
