Given this is a one time project of only several hundred Documents any
$49-$79 Flatbed scanner should do. Once you get into a grove you should
be able to scan 30+ documents per hour manually. For about $199 you can
get a flattbed with an auto hopper capable of feeding multiple sheeta
through automatically. However, the source documents would need to be
consistant in size, shape, etc to feed reliable.
As for the file type if disk storage space is not an issue .Tiff is a
good choice. BitMap (.BMP)files will take up a lot of space. JPEG (.JPG)
would require the least space.
Also, The Degredation with .jpg file would only be an issue if the file
was going to be edited and save often. Simple copying the original file
will not change it. If you opened the image to correct a blemish and
then save the overall picture can loose some clarity when being
compressed again the second time. If the images will not be modified
after being scanned .jpg is a good choice as well.
The time required to scan and save in each of the file formats will be
insignificant. At most 10 seconds variation between slowest and fastest.
The resolution selected is what makes the difference between a scan
taking 20 seconds or 2 minutes. For Text document a low 300DPI
resolution should be suficient. Maybe not though. Higher resolutions
would allow not only reading of a document but analysis of the paper and
handwriting if ever required. Remember the higher resolutions will also
make the files size much larger. A 20 second 300DPI .JPG file might be
75K verses a 2 minute 1900DPI .jpg scan swelling to 12MB.
Hope this helps.

Subject: Scanners -- again
Dear Friends,
Last August I asked advice about buying a scanner and external cd/dvd
burner
for my wife , but it turned out that the museum in question forbade
scanners! Grrr. So the decision was put off, until now.
Today I went out and bought an Epson Perfection 4490 Photo, for the
specific
purpose of scanning several hundred historical documents (mainly
letters,
handwritten). I have succeeded in scanning a document into my laptop,
so I
know that everything works, but my question is: what format should I
use?
JPEGs deteriorate with multiple copying--right? (That's what the
Epsons
instructions say.) Should I use BITMAP or TIFF? A major factor is the
time required to make an individual scan. Since we have hundreds of
documents to scan, we don't want this to stretch into July, but we also
want
good-quality files in a format that is widely usable. My test runs on
both
BITMAP or TIFF seem to take about 20 seconds per scan. Does that sound
right? Sorry to be such an ignoramus.
Any suggestions will be most gratefully received.
Henry Wiencek
