Title:
canon pixma MP970 TPU scanning stopped working
Status in “sane-backends” package in Ubuntu:

The scanning with the transparency unit fails consistently with
'operation was cancelled'.
I downloaded the source from http://git.debian.org/?p=sane/sane-
backends.git and used git bisect to find the first failing commit.

I can see there are indeed some changes in the pixma code at this
commit, but I don't know enough about the subject to see what's wrong.
It would probably be better to report it directly ion the debian bug
tracker of the sane project, but I don't feel like creating *yet
another* online account just to report a bug.
