I have two perfection pro scanners, one that handles up to 5 x 7 or 
larger and the other that handles 4 x 6.  there is
probably no need for regular fiche to get a scanner that can do 8 x 10 
in the epson line, because even
for aperture cards, which have the dimensions of holerith cards, you can 
scan it with both of the above.

I scanned a couple of fiche which were from the war department / US 
Navy.  They came out
pretty good.

they can be viewed on the page
as the fiche1 and fiche2 pdf links, and the "number one" and "number 
two" links.

I scanned from the 8 x 10 raw documents images on the fiche, to the same 
dpi as if I had
scanned an 8 x 10 page black and white at the same dimension.  Each scan 
scanned a physical area maybe 1/4" x 3/8" or so, maybe a bit smaller.  
The fiche was
14 x 7 images app.  The epson's optical resolution is plenty high enough 
as you
pointed out to accomplish this.

I had a reference grid in the software that allowed me to specify a 
single scan area,
and then move it from spot to spot to capture each successive page as I 

The results went to tiff, g4 compressed, then to pdf.  The web site has 
jpg and the
final pdf.  Each fiche took about 45min to 1H to scan this way to 
individual images.
