Tricia is doing the same thing I am doing, but you'll get more details.  So
try this command instead:

SANE_DEBUG_PIXMA=3D128 scanimage -v --format=3Dpng -o ~/Desktop/test.png

Understood. Can you re-run the same command but prefix it with<br>
SANE_DEBUG_PIXMA=3D128 ?<br>
<br>
This may give us more information about what exactly is failing in this<br>
process, which _might_ be an issue with backend/driver support for this<br>
scanner, but could also be something related to the configuration of<br>
your system.<br>
