Nearly all the major manufacturers have Windows 7 drivers
available. Your scanner may not
ship with the new drivers in the box however they are available
for download from the Mfr. website.
Fujitsu Scanner Technical Explanations of IPC and VRS
IPC (IMAGE PROCESS CONTROLS)
IPC is a Fujitsu hardware
based image enhancement board that comes standard with the M4099D scanners. It is an option for the
M4097D and the fi-4750C which may be purchased pre-configured in the
scanner (additional price) or as a field upgrade after the scanner is
originally purchased.
IPC DESCRIPTION
IPC is an Image Enhancement
Technology installed within the scanner allowing it to run at rated speeds
while processing the images. The concept of IPC is to enhance the images
during production mode without stopping the scanning process. Simply
select a setting that works best for your documents turn it on and leave
it on IPC utilizes 16 various settings such as
Background Removal, OCR Smoothing, Dynamic Thresholding etc.. which may be
used with one another to automatically process the
images so that the data is clear and easily read. (please see attached IPC
document for a full description) IPC also has 5 presets
designed for various types of popular documents such as NCR forms,
magazines and brochures, etc.. This allows the user to quickly select a
preset and scan all of their documents without
stopping or having to make adjustments to the images. If the customer's
documents do not happen to fall into one of the preset categories they may
create their own custom preset by choosing from the 16 settings in the IPC
menu.
IPC is extremely powerful and is
capable of scanning mixed batches of documents with excellent results.
However, although IPC can handle a wide variety of document types there
will sometimes be exceptions that may need further adjustments
which will require re-scanning. For example if you find a preset that
works well with the majority of the documents you
are scanning but then add a document that perhaps went through a bad copy
machine and has an extremely black background or a
document that has very light text because of a printer that needs a toner
replacement you may have to make an adjustment to
the scanners brightness or contrast levels for this exception document.
Outside of those extreme cases IPC is capable of
providing clear crisp images during the first scan with no re-scanning
required.
Document types that work well with IPC:
NCR Forms
HCFA Forms
Colored Paper
Shaded areas on the documents
Dot Matrix Printing
Forms with colored background boxes or shaded boxes
Scantron type sheets
IPC LIMITATIONS
IPC is strictly image
enhancement. It does not provide de-skewing and/or cropping and it will
not stop the scanning process due to image quality
issues. If the operator would like de-skewing capabilities they will
have to either use a Kofax Adrenaline board or Image
Controls software or rely on the imaging application to offer
de-skewing.
VRS (VIRTUAL RE-SCAN)
VRS is a product developed by
Kofax and is available on most of the Fujitsu series as either a
software based solution or as a software/hardware
solution. VRS Software must be purchased as an accessory to the scanner.
Hardware VRS is
a product that is distributed by Fujitsu through our normal distribution
channels and may be purchased pre-configured certain
models
VRS DESCRIPTION
VRS was designed with the goal of
eliminating re-scanning by allowing the scanner operator to intervene
during the scanning process and make adjustments on
the fly whether they be image quality or hardware errors. The user has the
ability to create profiles based on image quality
expectations and potential hardware errors such as paper feeding issues.
These profiles are then used during the scanning process and based on the
chosen profile the operator can actually have the
scanner stop during the scanning process, report the error to the user,
and allow the operator to make the necessary
adjustments to continue scanning. Since the images are being buffered
before being released to the application changes may
be made during the scanning process to enhance the quality of the image.
For example, if the operator is
scanning a set of documents that are of similar nature but then has a
document that has an extremely black background VRS
has the power to stop the scanning process based on that images
unacceptable quality. At that point the VRS interactive window would
appear and allow the operator to adjust the image quality based on brightness/contrast
control, either apply that new setting to the document or the remaining
part of the batch, release the image to the
application, and continue scanning. The adjustments regarding image
quality are based on the brightness and contrast of
the document being scanned. VRS allows the user to create a window or
threshold that will stop the scanning process if the
document being scanned falls out of the established range set by the user.
VRS TECHNOLOGY
VRS scans documents using
grayscale mode on the scanner delivering a very detailed image. Once
scanned VRS processes the image and then provides a
black & white image to the user's application. Therefore, VRS is very
powerful regarding the manipulation of an image. For
example, if you have documents that contain graphics in the background
however they are interfering with the data on the
image VRS can actually remove those graphics leaving only the desired
text. This also works well with official documents
such as Admission Records, Death Certificates, checks, etc.. that have
official logos or complicated graphics in the
background. Typically, image enhancement technology such as IPC will
interpret those graphics as data and therefore allow
them to remain within the image.
VRS also provides automatic
De-Skew and Cropping available on the hardware version of VRS
on-board the M4097D and M4099D. Since both scanners
use a black background in VRS mode they can de-skew up to 45 degrees and
crop the image to it's exact size even when scanning
mixed lengths in the same batch.
VRS does extremely well in
situations where the customer wants to eliminate the re-scanning process,
allow the operator to be alerted to potential
errors, make adjustments during the scanning process, and where documents
have either extreme brightness/contrast issues or
where the image needs to have either graphics or highlighting removed from
the document.
IPC on the other hand is designed
for the production environment customer that does not want to stop the
scanning process and is willing to potentially have
to do some re-scanning. Both technologies work extremely well and
definitely have their place in the market.
