[sane-devel] Pixma: ADF paper empty patch for Canon Pixma MX???

[Matthias Peter Walther]

Hallo Rolf,

I'm sorry, I couldn't reply earlier. I had some issues with my pc, hdd
crash.

I pulled the patch from the git and I can't get higher resolutions than
75 anymore while using the ADF. It resets the resolution back to 75 all
the time.

But the out-of-paper issues works great and the scaner recovers
perfectly from the error state now.

Could you look into that resolution issue please?
