Hi /iaw,
Yes, the Xerox /Visioneer Documate 262 is a Departmental rated scanner
with an attractive price and decent software suite. It comes with Kofax
VRS, Twain, and ISIS drivers like the Fujitsu product line.
Pros:
On paper the 262 is attractive- particularly the price for performance
category. For the most part, image quality is good thanks to the dual
600 dpi color CCD's (today's standard for document imaging). But, the
main feature is the speed of the ADF at 33pages/ min or 66
images/minute duplex. The DM 262 is an easy scanner to understand since
it's basically 2 CCD's on a quick ADF mechanism. The OEM designed
scanner can be found easily in other models (such as the Kodak i30/40
series).
Cons:
The DM262 only has length check available for detecting double feeds.
Document image scanners base caliber of product on the reliability of
the Speed, Quality of Images, Footprint/ size, Compatibility with
capture applications, ease of maintaining, and Paper Handling.The only
form of Double feed detection by the 262 is by 'Length Check'. If/when
the ADF multifeeds, unless you're watching every page feed through the
ADF like a hawk- double fees will slip through the ADF and result in
that file not containing the images from several pages. The speed only
increases the chances of missing important data in your scanned image
files.
Length check is a mechanical sensor which detects the size of each page
from leading edge to trailing edge. If there's a difference of 10, 15,
or up to 20mm from any 2 sheets in a batch, the scanner will alert the
software that a doublefeed has occured. If the batch contains
documents of various sizes (legal / letter mixed batches) then the
scanner would stop everytime it detected a fluctuation in page size or
severe skew- even if there wasn't a real doublefeed. The false-positive
condition makes it impossible to scan anything quickly unless you
disable the length check within the driver. The catch 22 is disabling
lengh check means there's no form of assurance that you've captured all
the pages fed through the ADF.
The CCD's only have white backgrounds to calibrate from. VRS can deskew
and autocrop documents printed on white paper scanned with this type of
configuration because the very slight difference in tint from paper
against this white background- but, not nearly as effectively as white
paper against black backgrounds. The 262 only offers white.
The 262 only has one consumable part- the seperation pad assembly.
Friction ADF scanners have 2 critical components for paper handling-
the Seperation pad assembly (to seperate the documents ensuring only 1
page feeds through at a time) and Pick Roller (the component which
actually does the pulling of the paper). Since the DM262 doesn't allow
for end user replacement of the pic roller, the life of the scanner is
limmited to the life of this part. It's like having a car without being
able to change the tires. Typical lfespan of this type of material is
100-200k pages or 1 year. (just about the same time the warranty
expires )
The Fujitsu fi-5120 and fi-5530C have ultrasonic double feed detection-
which actually detects pockets of air between 2 or more sheets. this
allows you to scan documents up to 34" in a mixed batch and still be
sure that everthing was captured. The dual CCD's on both scanners have
an internal mechanism which automatically switches the backgrounds from
white to black allowing VRS to accurately deskew and autocrop your
images to the actual size of their originals. Both also are designed
with 2 consumables: one pad assembly 100k page rating (usually about
$20) and one pic roller 200k page rating (approx $35) ensuring a long
life for your investment.
other notable features include an imprinter option is available with
both Fujitsu scanners vs. none for the DM productline.
Hope this helps~

... The price
Post by i***@gmail.comany experience with the xerox 262 scanner? it is still one third the
price of the nice similarly fast fuji 5530 scanner (and if I count in
the price of software, one-quarter), although it does lack the 5530's
100 page paper tray.
