Certified Scan Applications
As part of the certification process, Kofax tests VRS compatibility with a wide range of
scan applications. While the list of certified scan applications is updated on a regular
basis, it is important to know that VRS is designed to work with any application that is
based on ImageControls, ISIS, or TWAIN.
Certified vs. Non-Certified Scanners
When a scanner is certified for VRS, it goes through a rigorous testing process during
which the best default settings are identified and selected. For this reason, we
recommend that you use VRS only with certified scanners. You can use the product
page on the Kofax Web site to view the list of VRS-certified scanners. In addition to
listing the scanner name and manufacturer, the VRS product page includes the
following information:
Driver used for VRS 3.5 (TWAIN, ISIS, or Kofax SCSI)
Black or white background (black borders are necessary for automatic
cropping)
Additional memory required for optimal performance (if applicable)
Interface certified by VRS (SCSI, USB, or FireWire)
VRS is also capable of working with certain non-certified “compatible” scanners,
provided that they have been configured with the Kofax Source Manager (KSM). It is
important to be aware that you may experience less than optimal image quality when
using a non-certified scanner with VRS.
Not every scanner can be used with VRS. To be configured as compatible with VRS, a
non-certified scanner must meet the following requirements:
Ability to output a 256-level grayscale image as a single image.
Provide a TWAIN driver or an ISIS driver. While VRS works best with an ISIS
driver, it also supports some scanners with TWAIN drivers.
Note For more information about using non-certified scanners with VRS, refer to
“Configuring Non-Certified Scanners” in the VRS Installation Guide.
