4 VRS Installation Guide
VRS Scanners: Certified vs. Non-Certified
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. Also, Kofax Technical
Support is available only for VRS-certified scanners. You can use the VRS product page
on the Kofax Web site at www.kofax.com 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 (TWAIN, ISIS, or Kofax SCSI).
• Black or white background support.
• Additional memory required for optimal performance (if applicable).
• Interface certified by VRS (SCSI, USB, or FireWire).
VRS is capable of working with some non-certified or “compatible” scanners, if 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 compatible
with VRS, a non-certified scanner must meet the following requirements:
• Ability to output a 256-level grayscale image as a single image.
• TWAIN driver or ISIS driver support. While VRS works best with an ISIS driver,
it also supports some scanners with TWAIN drivers.
To use a non-certified scanner with VRS, you should install the VRS software
according to the instructions in Chapter 2. When prompted to select a scanner during
the VRS installation, select the check box labeled
“
I will configure my scanner later.”
You will need to install the scanner driver on your own, and then use the Kofax Source
Manager to create a source for the new scanner and make it available to VRS. After
