[sane-devel] Canon PIXMA MX870

[Nicolas Martin]

Slightly modified again file pixma_mp150.c (new attached) to add:

- maximum 600 dpi for generation 4 scanners in ADF/ADF duplex mode
- try to fix ADF empty scanner hanging. Not sure this will fix it, but
worth a try. Could you send back the scanimage.log you get now when ADF
is empty.
