<p>Hi JMS,</p>
<p>What SANE version is installen on your system? You need version
1.0.29.</p>
<p>If you're using Ubuntu or an Ubuntu clone, you can use my ppa to
update SANE: <a class="moz-txt-link-freetext"
href="https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git">https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git</a>
.
</p>
<p>
If you have another Linux OS, please install SANE as described in
INSTALL.linux (<a class="moz-txt-link-freetext"
href="http://www.sane-project.org/docs.html">http://www.sane-project.org/docs.html</a>).</p>
<p>Please try to scan all dpi resolutions and after this the
document feeder.</p>
<p>Hope this helps.</p>
<p>Cheers,<br>
Rolf<br>

<div>I'm trying to get a Canon TR4529 work with Sane without any
success. The support page said testers are needed. Here am I

<div>Scanner works well with scangearmp2.</div>
<div>sane-find-scanner can find it: found USB scanner
(vendor=0x04a9 [Canon], product=0x1854 [TR4500 series]) at
libusb:001:006<br>
</div>
<div><br>
</div>
<div>But scanimage doesn't return anything:</div>
<div><font face="monospace">$ ./frontend/scanimage -L<br>
<br>
No scanners were identified. If you were expecting something
different,<br>
check that the scanner is plugged in, turned on and detected
by the<br>
sane-find-scanner tool (if appropriate). Please read the
documentation<br>
which came with this software (README, FAQ, manpages).</font><br>
</div>
<div><br>
</div>
<div>I have downloaded the last snapshot and built from there.</div>
<div><font face="monospace">1008 27/08/2019 09:06:12
./configure <br>
1009 27/08/2019 09:06:37 make<br>
1013 27/08/2019 09:11:15 ./tools/sane-find-scanner <br>
1016 27/08/2019 09:11:37 ./frontend/scanimage -L</font><br>
<br>
</div>
<div>From documentation it says:</div>
<div>
<pre style="color:rgb(0,0,0)">The device name for USB devices is in the form pixma:xxxxyyyy_zzzzz
where x, y and z are vendor ID, product ID and serial number respec‐
tively.</pre>
</div>
<div><br>
</div>
<div>So I tried:</div>
<div><font face="monospace">scanimage
--device-name="pixma:04A91854_22811"</font><br>
</div>
<div><br>
</div>
<div>But I don't know what is the serial number. I took the one
from the printer, but doesn't work.</div>
<div><br>
</div>
<div>Can someone please provide some guidance on how I can make
process and how to help with the testing?</div>
<div><br>
</div>
<div>Thanks,</div>
