VRS Installation Guide
TWAIN and ISIS Considerations
All VRS scanners are supported by either TWAIN or ISIS drivers. Although some of
these scanners will work with both ISIS and TWAIN drivers, only the driver that
works best with VRS will be certified for use. If your scanner is certified with a
TWAIN driver, refer to
TWAIN Installations
on page 8 and follow the instructions that
apply to your scanner. It is not necessary to install an ISIS driver, as VRS includes all
the necessary ISIS software to control the certified scanners. For details, select the VRS
Supported Configurations link from the Support area of the Kofax Web site.
USB and FireWire Considerations
Some VRS scanners are supported by a USB or FireWire interface. If your scanner
requires a USB or FireWire interface, there may be specific installation instructions
that apply to your scanner. Refer to
USB and FireWire Installations
on page 9 for more
information.
