You can show us the output of lsusb when it is plugged in.

&gt; Hi, Joe.<br>
&gt; <br>
&gt; I would expect the scanner functions of this device are supported (if<=
br>
&gt; they are) via the pixma backend; but it&#39;s not explicitly listed as=
<br>
&gt; supported by the documentation.<br>
&gt; <br>
&gt; What is the USB device ID for this device? You can double-check if it&=
#39;s<br>
&gt; listed in the documentation<br>
&gt; (<a href=3D"http://www.sane-project.org/man/sane-pixma.5.html" rel=3D"=
