VRS Getting Started Guide
Introduction
This guide gives you instructions for installing the hardware and software components of
VirtualReScan (VRS).
Product Overview
VRS makes high-volume scanning easier and more cost-effective than ever. With automatic
detection of poor image quality, VRS performs automatic image enhancements that greatly
reduce recognition errors. To ensure that every scanned image can meet your standards, VRS
provides an interactive settings control that eliminates the guesswork with easy, real-time image
correction.
Other features include the ability to scan batches that consist of multiple document sizes or
varying degrees of quality, as well as the ability to automatically assign contrast and brightness
settings that are optimal for your document type. If specified, VRS can even remove color that
may interfere with the data you are collecting. VRS will also detect paper jams, bent corners, and
equipment conflicts. It is no longer necessary to pre-sort mixed batches, and in addition to the
time savings, post-processing accuracy is increased and storage requirements are reduced.
For batch scans in which Optical Character Recognition (OCR) precision is crucial, as it is for
database-bound information, low-contrast documents traditionally pose significant problems.
With VRS, you can enable "Intelligent Contrast / Brightness Adjustment" and process the batch
with confidence, knowing that every low-contrast image will be adjusted automatically to the
acceptable level of quality required for OCR.
In addition to Intelligent Contrast / Brightness Adjustment, VRS offers a range of features to help
you ensure the highest level of quality for every scanned image:

Step 2. Install the Adrenaline Hardware Accelerator
This section explains how to install the Adrenaline Hardware Accelerator.
Note: To run VirtualReScan successfully, you need to install only the software provided on the
VRS installation CD. Do not install the software provided on the Adrenaline Hardware
Accelerator CD.
Compatibility with Current Accelerators and Engines
We recommend that you install the Adrenaline Hardware Accelerator on a PC with no other
Kofax hardware accelerators. If necessary, remove the older Kofax accelerators before you install
the Adrenaline Hardware Accelerator.
Precautions
When handling your Adrenaline Hardware Accelerator, follow these precautions:
•
•
•
Keep the accelerator in its original shipping package until you are ready to install it.
Power off your PC before installing the accelerator.
Before handling the accelerator, discharge static electricity from yourself and the work
area by touching the metal chassis of the PC.
•
Hold the accelerator by the edges; do not touch its metal surface.
Before installing the accelerator, make sure your PC is powered off. Then, install the accelerator
in any available PCI slot. Be sure to use the screws to secure it into place.
