Thanks.  It is very similar to Farvil's log and I could fully extract
the image (it reads "Luciano González Parra").

Please increase the verbosity level with something like

$ ./pixma_scan -o test.pnm -v 3

and post the output.

Oops, that shouldn't happen, since the driver only touches interface 0.
When [1] is correct, usb-storage should be interface 2 and usblp (the
printer) interface 1.

To eliminate as much problems as possible, I reset the bus on startup --
just for the time being.  Maybe that's why the kernel tells us something
about the storage interface.  Mhm...!?
