[nfbcs] flatbed scanner recommendation

[Bryan Schulz]

Hi,

I also agree that Epson is a good choice.
I have a workforce 545 and it has usb and rj45 ports.
I use openbook for scanning and it turned out to be at least 50% faster than
the hp Scanjet.

At home I use an Epson V100 scanner. It has worked in Windows XP, and now I
use it in Windows 7 with Omnipage 19. It interfaces using USB, rather than
SCSI. It comes with software that pre-scans the page to determine whether
this is a set of photos, a color document or a B&W document. It then sends
it along to Omnipage. It is several years old, and replaces an HP SCSI
scanner which I bought back in 1996. I'm sure it is long out of production,
but the price was somewhere below $200. 
If Tesseract can deal with color images, I would look for a scanner that can
do color or grey-scale at 300 or 400 dots per inch. Conventional wisdom used
to be that this was the sweet spot for good OCR. A higher resolution may
only increase the amount of noise superimposed on the printed characters.

Anybody have a recommendation for a flatbed scanner for use with OCR?  I 
don't do a whole lot of scanning. Sometimes I scan my mail. Sometimes I 
scan in books. I probably don't need a top of the line system. But I 
don't know if I should be looking in the $200 or the $400 or the $800 
price range.

I also don't even have a Windows machine. I use linux with the tesseract 
OCR engine. So the software that comes with the scanner will probably be 
of no use to me.
Feel free to recommend a scanner even if you don't know if it's linux 
compatible. I'll check that.
