Making good ADF scanner

[Suprmedo]

I'm sure this was asked before but i will ask anyway.

I would like to undertake a big scanning project of book scanning, but
don't have enough money to buy expensive scanner. The plan is to
strip books of its bindings and put them in automatic document feeder.
The problem is that most feeders only take about 50 sheets of paper
and not more. Scanners that can take up to 500 sheets cost more then
$10.000. Is there any way i can buy a scanner and feeder separately? I
would like to buy ADF that supports 500 sheets of paper and is not so
expensive and mount it on not so expensive scanner, hopefully this
combination, if it is possible will be far less expensive.
The next problem that i have is that recommended use for low end
scanners is 1000 scans per day. Scanners that can do 10.000 are again
more then $10.000. Where exactly is the problem ? Do chip scanners
burn out there light bulb or do the scanning sensors burn out ? If the
problem is with light bulb , wouldn't it be possible to replace it
whit chipper one for instance with LED's ?

Well if what i wrote is possible how would you guys do it ? What
feeder with what scanner would you use, how would you fix chipper
scanner so that it wouldn't burn out ?

Thanks for all the info, i hope someone know's how to do this and will
be able to help me.

There are scanners that support ADF, and you can buy the ADF unit
separately.

There are Book scanners than you do not have to cut the spine.
In the $300 price range.

Much more expensive.

You can also use a digital camera and copy stand.
7 megapixel cameras and up should be a good image.

Copy stands:

Get one with lights, makes the job easy.

Thank for replay.
While Plustek OpticBook 3600 is good a book scanner, it would take me
forever to turn pages and scan all the books I need to. If i can use
document feeder i can scan 50 pages a minute so i could easel port 50
books a day to searchable pdf files, its true this would strip books
of its bindings but process would be much faster.
I guess i have to specify my questions. How can i make ADF scanner
that will be able to scan at least one book a a time (250 sheets)
without having to change book pages all the time since ADF won't be
able to take in more then 50. And if i get chipper scanner working
with bigger ADF how can i make sure that scanner wont burn out if it
scans 10.000 pages per day.

Thanks again

Are you also looking for something that will turn each page so that
recto and verso of each page are scanned before moving on to the next
sheet? Also, 50 ppm is very fast. A camera can do it, not an
inexpensive scanner.

If you can 're-feed' the ADF during processing, you could perhaps work with
a cheap scanner.
Like, when the scanner processed the last 5 pages, just drop another 30-40
on top of the stack.
Or maybe put these 30-40 'under' the current stack... depending on whether
the scanner
pick the sheets from the bottom or top of the stack

You would probably have to test-drive a few cheap ones to see if they work.
Problem is that (especially the cheap ones) test-driving scanners is
something not many shops do...

And to makes matters slightly more complicated: what about duplex scanning?


PS: Buying a separate ADF and another scanner is a recipe for disaster.
ADF-units usually work only with one specific type of scanner.
Only with the more expensive ones (Epson gt-xx000 range and so on) you
sometimes can migrate your ADF to the next version of the scanner.


Anyone knows if a Fujitsu Snapscan S500 allows for 're-feeding' during a
scan-run?
From the messages in this group I seem to understand that this is quite nice
sheetfed scanner.

In my experience (with a good but inexpensive scanner and a fast Mac)
the scan-OCR process is more like *one* page per minute; certainly not
anywhere near 50. And that doesn't count the almost mandatory visual
inspection and correction part of the process. You do realize that if
you don't do OCR, you won't have searchable PDFs?

Maybe a 50-page capability isn't all that limiting, since you'll only
have to reload it about once per hour.

Yes i do understand that i will have to do OCR but thats a different
job for computer not scanner, when you say mandatory inspection is
necessary, thats true but i'm not looking for 100% accuracy just the
ability to search. Bennett Price you say camera could do it, but how
would you automated the process?

I wont be able to replay for couple of days but, i hope someone will
write helpful suggestion ?

Thank you all

Have you considered leasing/renting a machine that will do duplex
scanning and have the speed you need?

Maybe you could contract with Google to do your scanning. Apparently
they've devised machines that can gobble books automatically.

Also, factor in the cost of an industrial paper cutter since you'll most
likely have to trim the ripped out pages so they have a very clean
edge; otherwise you're likely to have lots of misfeeds.
