<br>
Please report if both, (1) 1200dpi scans and (2) scanning from document<br>
feeder are working. You scanner still is marked as "untested"<br>
(<a href="http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA" rel="noreferrer" target="_blank">http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA</a>).<br>
<br>
I wouldn't use Ubuntu's deb packages for Debian. You need libjpeg if you<br>
e.g. want to save images as jpeg from scanimage. Please install from<br>
sources as described in INSTALL.linux<br>
(<a href="http://www.sane-project.org/docs.html" rel="noreferrer" target="_blank">http://www.sane-project.org/docs.html</a>).<br>

Many thanks for your help.<br>
