Problem: The installation will not complete successfully. If installation finishes, the scanner’s OneTouch 4.0 options do not seem to work properly. What do I do?
A likely cause is that some driver programs are already installed on your computer for another scanner. They are interfering with the installation and OneTouch options, and you need to remove those other drivers and re-install your Visioneer 9420 USB scanner. Please see the documentation that you received with the other scanner for the steps to remove its driver programs. You can also use the basic steps in the section “How to Uninstall Your Scanner” on page 138, but in Step 3, instead of uninstalling OneTouch 4.0, uninstall the other scanner’s driver programs. After uninstalling the other scanner’s driver programs, uninstall OneTouch 4.0 using the steps on page 138, then reinstall it using the steps on page 8.
