ROUBLESHOOTING
In addition to the troubleshooting information contained in this section,
please see the Readme file on the Installation Disc 1. The Readme file contains
additional information that may help you diagnose problems with the scanner.
Also visit our web site at www.visioneer.com for additional technical
information.
Problem: The scanner won’t scan. What’s wrong?
Check for one of these possible problems:
■ Are the cables loose or not plugged in securely? Inspect the cable
connections. Make sure the cables are plugged in securely.
■ Is the scanner’s status light on? Turn on the scanner’s power. If the
status light doesn’t come on, plug the power supply into another
electrical outlet.
■ Did you restart the computer after installing the software? If you
didn’t restart the computer, it may not have loaded all of the software
files. Try restarting your computer.
■ Did you plug the scanner into a USB hub? If you’re using a USB hub
to connect the scanner, the hub must have its own power supply. If the
hub does not have its own power supply, plug the scanner into a USB
port on the computer.
■ Did you select another scanning source from a TWAIN application?
If you use multiple devices with your computer, you may have selected
another source for images with your TWAIN scanning application.
Make sure your Patriot 780 scanner is the selected scanning device.
■ Did you set up the scanner properly? If the light on your scanner is
flashing, turn off the scanner, plug in the ADF cable and unlock the
scanner. For setup instructions, see the section starting on page 7 of this
User’s Guide .
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
the OneTouch options, and you need to remove those other drivers and re-
install your Visioneer Patriot 780 scanner. Please see the documentation that
