I have the Epson 1250 Perfection USB scanner "working" -- i.e., the
scanner runs and sends data which I can see sort of resembles the
image I'm scanning. However, the results strike me as much more than
a "calibration" problem. Please take a look at:
http://www.tomhull.com/scan1.jpg
This is a 40k jpeg reduction of the scan of a book cover which is
mostly black text on white background. As you can see, overall there
is a lot of red, and there is a lot of banding. When I fiddle with
the xsane brightness controls, it looks to me like the red channel
is coherent but oversaturated; the blue and green channels, OTOH,
show the banding but no coherent image.
My plustek.conf file matches the one posted by Gene Heskett, including:
option lampOff 600
option warmup 180
option lOffOnEnd 1
However, once the lamp comes on it stays on indefinitely. (Turns off
when rebooting.)
