Wow. That's fiddly. I can understand things being difficult - the

Speaking of fiche scanning, I was going through some boxes last week
and ran across the source fiche for VMS 2.0. I know it's far from the
only copy in the world, but it did make me wonder if anyone has an
electronic copy. It'd be a hell of an OCR project (or an interesting
Captcha dataset), but even scans could be interesting to read through.
What I have is one 3-ring binder with a special fiche-storage insert -
you can read the top 1/4" to see that you have the right fiche, and
the lower 90% is protected from dust and scratches. There's at least
20 fiche to a "page" in the notebook, and it's one or two
"pages".
Elsewhere, I know I have VMS 4.0 and probably other versions of source
fiche. Of course, I do have a reader (more than one), but looking at
things on a modern machine without having to go to where the gear is,
make room to set the reader up, etc., means that most of the time, the
fiche just sit - no casual browsing and no easy way to share or
preserve the contents.
I know the group has hashed and rehashed fiche scanning and I don't
mean to re-open that debate. Obviously fiche scanners exist,
reinventing the wheel isn't cost effective, etc, etc. It's
unfortunate that there's so much manual fiddling to get a good scan,
but those letters are awful tiny.
If I were on the left coast, I might consider volunteering to drive
the scanner just to be able to share the results. I have a pile of
fiche myself, mostly from the late 1970s through the mid-1980s, IBM
and DEC docs primarily, and it would be great to know that it's not
only accessible as slivers of film.

I have an epson perfection scanner which can scan up to 5x7 transparancies.
Once I have the template set, I can do a fiche in about 5 min.
If you can snag one of these with the appropriate size transparency
capability of any size, I recommend getting it, as it is very fast. I
don't know what exists for sheet feeders on this scanner, but I would
think with a sheet feeder, you could do 10 pages / min minimum for full
size sheet scanning as well, not bad considering you could do both.
I had one of Al's high speed Ricoh's for a while, and the real problem
you get into is that manuals which have been stored for a long time, and
are not offset print (ink) but are xerox or such printing the pages will
be stuck enough to keep you from using the real full speed of his
scanners. I ended up having to do a sheet by sheet feed with mouse
clicks per page anyway to scan a manual. Admittedly it was a very fast
process, but not that much faster than the above.

I am reasonably certain that the individual letters are small enough
that even "modern" consumer grade scanning gear will make a hash of
things.
Please note that at no time did I ever propose using anything other
than professional grade gear on these fiche. I remember the endless
debates and I wasn't trying to suggest that we've miraculously come
into an era of new techniques.
Consumer-grade hardware has gotten lots cheaper (my first scanner was
$800), but the quality has bottomed-out to "adequate to make copies
for later reprinting". Slide scanners are pretty good these days, but
they are optimized for a 35mm frame, and even then the attention is on
color reproduction and dust/scratch elimination, not resolving details
a few hundred microns across.

If this is right, then there's a scale factor of about 1:90 to 1:100
involved. That should tell everybody why even a good consumer-grade
scanner will not do the job. To get the equivalent of a 300dpi scan,
you'd need to have about 30000dpi. Nothing any el-cheapo scanner could
handle. (Let alone the problem of getting the sheet properly into the

So in the top-bottom direction, we have:

J-B read that as the size of the whole fiche (with lots of A4 images on it). I think you
actually meant that each page image is that size.
The truth is most likely in between: page images (on DEC fiche at least) are a bit smaller
than that, and also they are usually images of line printer size pages (A3, not A4). So a
2400 dpi scanner is about a factor 3x too low for acceptable quality. (And yes, that
ignores other issues like ability to hold the fiche flat enough and focus well enough.)

Yes, there are step and repeat scanners made by companies like Canon
and Mekel. They are expensive. I have a first generation model Mekel
that I paid over 10 thousand dollars for (which is a fraction of its
new price). DEC used very small frames which require a lot of fiddling
to get the parameters set correctly. Scanning services exist, but the
test scans I got from them were not well aligned.
I have fiche for most of the RSX and VMS releases up through 5.0, and
several sets of the blue FE fiche kits, layered products, etc, etc but
it takes a VERY long time to do anything with them. Since I can scan
thousands of pages of paper per day, guess what gets done?
The "low cost" (ie. 1000$) scanners are modified desktop fiche readers
that work like the xerographic fiche printers (mirror which flips to
a drum) and are manual positioning.
As I've found with paper scanners, the low-cost ones are barely usable.
You need to find a "pro" one used to get any sort of throughput, then
enjoy expensive or non-existant hardware support (the Panasonic KV-S3065
I'm using now is the first scanner I've had that I was able to get a real
service manual for) and expensive software (the blueprint scanning software
cost as much as I paid for the scanner).

This might be way off base since I don't know the particulars, but is it
not possible to overscan each page and then crop after it is in digital
form? Why spend a long time fiddling trying to center and align each
page optically?
Also, I'd be willing to kick into a fund to hire a kid to sit and do the
fiddly stuff, and I bet others would too. There is no reason for you to

I've had this done for me for some historical fiche for something I'm
writing. The photo's were taken with a 6MP Nikon D70s. It works, but it is
far from ideal. Still it is preferable to the cost of printing out the
individual sheets if you have someone that will be visiting a library with a
copy of the fiche you need. Room illumination would have been standard for
the library the fiche was at.
To do it right, even this solution isn't cheap. You need a good camera with
either a remote, or wired trigger, and the camera needs to be on a tripod.
I have my doubts this would work well for anything like source code fiche.
DEC fiche tends to be very small.

Even a decent, older fiche scanner can bring over $15kUS for the

on microfiche ranges from moderate, say 100 8.5x11 source pages per
fiche, up to several hundred pages per fiche. To be able to scan such
a broad range and still pick out the characters reliably is quite a
feat.
A big part of the problem with scanning tech docs from fiche lies in
the fact that it's difficult to lays hands on high quality duplicates.
Silver originals or even silver duplicates would be the best case
scenario, but don't really see them being made available for scanning.
Companies are reluctant enough to release master copies for first
generation duplication.
All of that having been said, I do have direct access to a fiche
scanner. Given decent, consistant fiche, it takes just over a minute
to scan a full fiche, at 300dpi (original. Scan an 8.5x11 image from
a fiche, print it back out at 300dpi, and you'll have an 8.5x11
document), bitonal. Greyscale takes a bit longer, but is sometimes
well worth the extra time investment. If anyone is interested, I can
entertain work requests as side-jobs. However, I cannot do it for
free. I still have to pay a use fee to my company for use of the
equipment.
