[Bug 1096612] [NEW] canon pixma MP970 TPU scanning stopped working

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Rolf Leggewie (r0lf):

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.

    color and grayscale negatives scan in TPU mode
    for CS8800F and CS9000F

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.
