VRS User’s Manual

As part of the certification process, Kofax tests VRS compatibility with a wide range of 

scanning applications. While the list of certified scanning applications is updated on a 

regular basis, it is important to know that VRS is designed to work with any application 

programming interface. 

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 links on the VRS 

product pages 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 pages include 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.
