[sane-devel] Pixma problems: 1200dpi Grayscale and batch mode

I tried moving the MP730_PID and DEV macro from pixma_mp730.c into
pixma_imageclass.c but the scanner would not operate at all. It attached to
the endpoints correctly and could read and write URBs but when it came to
sending the read_image command (0xd420) it responded with a cancel command
(0x1515).
The other imageCLASS devices are all limited to 600dpi which fits their
specifications but the MP730 is capable of 1200x2400dpi optical. Maybe the
imageclass driver is not the best reference for MP730.
Back in the pixma_mp730 driver, when I run a test scan at 1200dpi Gray, it
reads some image data then the scanner just keeps sending OK messages
forever. It may be a hardware bug. Here is what it looks like:

Regarding the ECANCELED error code on completion, this is the end of a
successful scan. The image data is fine but the driver sends an
abort_session command on completion

I have managed to get some success by adding a small sleep to pixma.c but
I'm still testing that.

Moving from the "MP730 driver broken since pixma-0.12.2" thread...

Concerning points 1 and 2 you raise, this is interesting:
The pixma_mp730.c file has been left almost untouched for a while (no
requests or testing ability so far), so it may be in a less "enhanced"
state than other ones covering more recent Pixma models, that have been
recently updated.
Dennis Lou wrote a while back the pixma_imageclass.c file, based on the
pixma_mp730.c file, and which covers several Canon ImageClass models in
the pixma backend. The code has been nicely brushed up, and is now in a
better shape than mp730's one.
So for the 2 issues you raise, I'll take a look and compare the
pixma_mp730.c code with pixma_imageclass.c and pixma_mp150.c , probably
will help a lot to solve those issues, thanks to your cooperation for
testing and feedback.
