Hi Timothy,
Very good questions~ and I'll do my best to answer:
The UltraSonic Double Feed Detection of the Fujitsu fi-5220C is error
proof.. It's the only technology available today on cutting edge
scanners which detects pockets of air between 2 or more sheets.
The old technology was based on 2 crude techniques- length, thickness
(or InfraRed) . I believe the Kodak i65 only has length detection
available.
Other disadvantages of the i65 are:
- only has white backgrounds which is a large disadvantage for
autocropping and deskewing the images accurately.
- ithresholding lite vs. Kofax VRS - VRS tops iThresholding by far. If
you'd like to see a quick demo, just let me know. Kofax VRS is the only
image enhancement technology which allows for dynamic image enhancement
allowing the user to view the changes to their images real-time.
iThresholding is still a guess at a preset, then scan. If the image is
poor, then the batch would need to be scanned again. The ROI is huge
when you think about lost time rescanning batches multiple times....
The fi-5220C has black reversable backgrounds for optimal cropping,
deskewing, etc...
and the UltraSonic DFD doesn't slow the scanner down at all- unless
there's a double feed. Another highlight to the ADF on the 5220C is
that it's the first ADF scanner that certifies scanning of Embossed
plastic cards (such as credit cards, insurance cards, ID's,,,) The
optics are also superior with the 5220C @ 600dpi True Optical CCD x 3.
If the spine of the books can be chopped, then I'd highly recommend the
5120C instead. It's exactly the same without the flatbed and around
$500+ cheaper. If your duty cycle is going to excede 2,000 pgs/day then
look into the fi-5530C (3,000 pgs/day) or fi-5650C (8,000 pgs /day).
Hope this helps...
