<div dir="ltr">Hi Rolf,<br><br>Thanks for the guidance. Build time is not an issue. So I built with all the backends.

<br>
With my patch please also test scanning from ADF and send me a logfile.<br>
<br>
For ADF scans I prefer gscan2pdf:<br>
$ SANE_DEBUG_PIXMA=11 gscan2pdf 2> tr4500-adf.log<br>
<br>
These tests are for the pixma backend using USB connection.<br>
<br>
Many thanks for your help.<br>
