I recently noticed just how high the resolution is getting on the
latest scanners. Epson has scanners various scanners in the $450-800
range that do the following resolutions 6400x6400, 6400x9600, and
4800x6400 Optical DPI.
The $800 V750-M Pro seems especially suited to Microfiche as it looks
like it can handle up to 8x10" film at up to 6400x9600, with the
correct orientation of the fiche being scanned I think that would
allow between 150-200dpi per page. It even supports Firewire as well
as USB.
Has anyone had the chance to see if these newer scanners can handle fiche?

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
http://vpb208.org/Diaries%20and%20Documents.html
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
physically
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
scanned.
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.

The scanner would be used for more than just microfiche, which makes
the 8x10 capability desirable.

The physical dimensions on the fiche was such that there were 14 8 x 10
sheets across a fiche. I don't have
the fiche around to look at and measure.
remember 8 x 10 transparentcy is a huge amount of data at high
resolution. most film negatives
are no where near that big.
I bought the scanner I have to scan 5 x 7 glass photo negatives from the
1800's that are
in my family, and that is the largest format I have. I only ever used
and could afford
4 x 5 negative film when i was shooting anything larger than 220 roll
film, so I have
very little larger than that.
the scanner will handle legal size, I think but not photo transparencies
that large.
What I meant to say earlier was the the scans when I finished had the
same bit dimension
as if one had scanned 8.5 x 11 sheets of paper, black and white at 200
dpi (IIRC).

Hmm, that's interesting. We're still on the look-out for something that can
scan DEC fiche, which IIRC is 16 x 13 pages per fiche. Of course the actual
scanning's only half the problem - there's also the issue of feeding the data
in and out of the scanner if it's going to be used for any kind of
preservation work, rather than one-off scans.
We've got about a million ICL fiches too that could benefit from scanning, but
luckily those are just a single A4 page per fiche and so a little more manageable.

Right now we're having fun trying to figure out how all the data's indexed -
we've got all these cabinets full of cards, but no apparent master index that
we've yet seen (early days though, plus we're in touch with Fujitsu to see if
they've still got anything on their site)
We *might* actually have CLAN 4 docs on paper already - I'll try and remember
to look when I'm on-site next and have access to the building that I think
they're in (I'm *sure* I've seen some somewhere, and have a feeling I know
which box they were in)

ICL? Does that perhaps include the CLAN 4 ? I'm looking for years for
docs on that machine.

That would be so cool!
Would you be able to get me a copy of some sort? Either hard or soft?
