Hi Theodore,
you're correct with these impressions. As the release date of SANE-1.0.9
is right ahead, I concentrated my work on fixing stuff that touches already
working devices. As the Canon devices are using other sensor chips as
other manufacturer, there's lot of work to be done to make the calibration
stuff working for them. But after releasing SANE-1.0.9, I will start with the
improvement... (Probably backend version 0.45)
The other point LM9833 or LM9832. I'm not sure what's really inside.
On one hand, there are two models N670U and N676U, this might implies
two different chips inside (LM9832 inside 670 and LM9833 inside 676).
On the other hand there's a mail earlier this year, that somebody managed
to open the scanner and found a LM9833 - so what?
Anyway in general this should make no difference, as the code expands
the 14bit (LM9832) to 16bit, and at least this is the only difference between
the two ASICs.
By saying "You are right", I meant that I have already noticed, that the
1240 is rather an upgraded 670 and should work with a couple
of code modifications. But this has to be tested...
regards
Gerhard
