It is actually 200-400 equivalent dpi depending on the magnification
required for the fiche. I haven't found any documentation on the 460,
but the newer versions ($75k) use a 4000 or so linear CCD and scan
the fiche in strips. The strips are stitched together in software,
and the individual images are cut out. This is a production scanner
as compared to the Canon MS3000 where the operator lines up a single
image and presses the scan button.
I'm so excited I can barely wait for it to appear upon my doorstep :)

400 dpi does not sound at all adequate. If we were to assume that the
microfiche were to be 1/10 (linear) the size of original paper (.85" x
1.1"), then we would want 10 times the resolution (linear) per inch that
we would want for original paper. Therefore, if the microfiche were to be
1/10 (linear) the size of paper (approx 1" square per frame), then that
would be like scanning pieces of paper at 40 dpi. Anybody know offhand
what the conventional sizes are for microfiche? (it's certainly less than
1" for the height of a frame!)
When will you start scanning fiche for a fee?

The question is: What do I now own?
<grin>
Google says $85K in 1996, very well-reviewed?
Up to 400 dpi, 2,000 frames/hour? Yee-haw!
