<p>Hi Petr,</p>
<p>Today I added your scanner to SANE sources. <br>
</p>
<p>You can rebuild SANE from sources now, or if you have Ubuntu or
an Ubuntu clone, you can update SANE from my ppa
(<a class="moz-txt-link-freetext" href="https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git">https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git</a>)
tomorrow.</p>
<p>If you might have any problems, please create an issue here:
<a class="moz-txt-link-freetext" href="https://gitlab.com/sane-project/backends/-/issues">https://gitlab.com/sane-project/backends/-/issues</a> . It's easier to
use the issue tracker than using the mailing list, if we need to
exchange any logfiles.</p>
<p>Please also report when your scanner is working.<br>
</p>
<p>Hope this helps.</p>
<p>Cheers,<br>
Rolf<br>

<p>Dear developers,</p>
<p>I have a Canon i-sensys MF724Cdw multifunction device, which is
recognized by <code>sane-find-scanner</code> as:</p>
<p><b><code>USB scanner (vendor=0x04a9 [Canon,Inc.],
product=0x27b5 [MF720C Series]) at libusb:001:005</code></b></p>
<p>Unfortunately, it is not recognized and supported by SANE.</p>
<p>I have investigated in the supported device list and found the
most of Canon devices is supported by the <code>sane-pixma</code>
backend, namely i-SENSYS MF730 Series (0x04a9/0x27e4) has status
Good (as Ethernet and WiFi have not been tested yet).</p>
<p>Neither i-SENSYS MF720C Series nor i-sensys MF724Cdw
(0x04a9/0x27b5) is mentioned in the compatibility table, so that
no backend supports them at the moment.</p>
<p>What is necessary to do to support these model?</p>
<p>I guess it should be supported by <code>sane-pixma</code>
backend as well, perhaps only its ID is missing in the backend
code.<br>
</p>
<p>I have tried to find some contact details to <code>sane-pixma</code>
backend authors - no success (lot of broken links or pages
updated ten years ago).</p>
<p>I am not sure if <code>sane-pixma</code> backend is maintained
in general.</p>
<p>I can contribute with testing if necessary.</p>
<p>Thanks for any info and/or contact,</p>
<p>Petr<br>
