Assuming an 8.5" page is fiched at 0.25" (I don't have the
exact figure handy), then to scan it an effective 200dpi,
you would need 6800 dpi, both dimensions, for the fiche.
If when scanning you use a photo depth of 8,24,or 48 bits
at the 200 dpi you can then later up the resolution to nearly
600 dpi 2 bit printtext depth if you want to with just minimal
losses.
Your 3200 dpi scanner would work with 8.5" pages fiched
at 0.5", but I don't think there were any done like that.
