    <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>

        <div>I'm trying to get a Canon TR4529 work with Sane without any

        <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

        <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>

        <div><br>

        <div>I have downloaded the last snapshot and built from there.</div>

          <br>

        <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

        </div>
        <div><br>
        </div>
        <div>So I tried:</div>
        <div><font face="monospace">scanimage

        </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>
