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

Mon Mar 17 20:03:08 UTC 2014

Hello All,

I had some trouble to apply the new patch, but Rolf helped me to fix it.

Here comes the result with git + patch pixma_mp150.c.patch1, 3 pages in ADF.

It works correct, but the timeout at the end acts weird. In the log it
counts down 8 7 6...but between each line it pauses around 15-20
seconds. This scan took ages!

The log comes as attachment.

Bye
Matthias
