[sane-devel] Canon MP470 support

Mon Feb 11 21:23:12 UTC 2008

Hi Ashwin!

That's good news too then!
For sure, the libsane rule needed to be adjusted for PID 1723,
corresponding to MP470.
When the Sane driver will be updated with the changes for recent Pixma
MFPs, the libsane
rules will be produced automatically when compiling Sane, provided that
the .desc files are 
correctly set up.

For the y-axis point, maybe I did not catch exactly the issue. 
You must know that the driver rounds up the scan dimensions to 32
(needed by Pixma protocol), 
so this will be more sensitive at low dpi than at high dpi values. But
the rounding should be rendered
by the Frontend anyway (Xsane does it)
Be sure to have the Y top left  parameter to 0.000 in the "Sane standard
options" window, in order 
to have the scan starting at the very top of the page.

Thanks for your feedback.

So as a summary, we have now those additional Pixma MFPs working, to be
added to the Sane files, and 
that seems to present optimal or satisfactory results:

MP610
MP520
MP470
MP210
MP710
MP740

Would be nice to have feedback for MP140 too, if anyone has got one, as
it looks that this competitor has great
chance to be working with this driver too ;-)
