I'm trying to make a Umax 3420 scanner work with SANE. It is a USB device
with an LM9832. I have made it turn the lamp on and off and do some scans
(at least a lot of the time; sometimes it doesn't seem to be driving the
stepper correctly), but so far the image data, while showing a recognizable
shape, is way off. So I'm trying to figure out how the calibration works,
and how the sensor gain/offsets are set. It looks like, besides finding
the calibration areas for the scanner, I also need to know the CCD type,
but do not know how to identify it. I've looked and it is unmarked. It's
in a 22 pin DIP, in case that narrows it down any.
