<br>
The Pixma backend just doesn't support 600x1200dpi. Sorry, this was my<br>
fault.<br>
<br>
Please patch the source backend/pixma_mp150.c with the attached file and<br>
try ADF scans again. I suppose that Canon changed ADF data format for<br>
all new scanners.<br>
<br>
Hope this helps.<br>
<br>
Cheers,<br>
