[sane-devel] Canon MX430 / MX510 / MX925 - does not recover when ADF out of paper

Hello Rolf,

I created three more logs.

And the timeouts are not fixed. In fact it's gotten even worse,
scanimage is captured in an (infinite(?)) loop of timeouts of which each
loop takes several minuites. Watch log "3rd_try".

Bye
Matthias
