User Guide

Did you plug the scanner into a USB hub?
If you’re using a USB hub to connect the scanner
try plugging the scanner’s USB cable directly to the back of the computer. It is not
recommended that you use the scanner with a USB hub, if you are using a hub, the hub must
have its own power supply.
•
Is the USB cable 6’ or less?
If you are using a USB cable that is longer than 6’ you may lose
connection to the scanner. The recommended USB cable length is 6’ or less, the USB cable
provided with your scanner is within this range.
•
Did you select another image source in the scanning software?
If you use multiple
imaging devices with your computer, such as a camera, all-in-one printer, or another scanner,
you may have selected another source for images. Make sure Xerox
®
DocuMate
®
3220 is
selected as the scanner.
Problem
: Why does my scanner not function after performing a system restore on Windows?
The system restore process may have corrupted some of the driver components. It is
recommended that you reinstall your scanner driver. Please refer to “Uninstalling Your Scanner” on
page 36 for installation instructions.
Problem
: Why won’t my scanner buttons work after scanning with Windows Image Acquisition
(WIA)?
After performing a scan using the WIA interface you must close the application you were using
before scanning with the buttons on the scanner. This does not occur when scanning using the
TWAIN or ISIS interface.
Problem
: Why won’t my scanner work after the computer has been sitting idle for several hours?
To resolve the problem, simply turn off the scanner power then turn it back on again.
This may occur after Windows goes into power saving mode to “hibernate” the computer into a
low power state. When you move your mouse or type on the keyboard it “wakes” the computer
back up and restores full power to the system. This power fluctuation during the computer’s
hibernating period may sometimes cause the scanner to lose communication to the computer.
Problem
: The installation will not complete successfully. If installation finishes, the scanner’s
OneTouch options do not seem to work properly.
A likely cause is that some driver programs are already installed on your computer for another
scanner. Or you previously had another Visioneer
®
or Xerox
®
scanner and that driver program is
still on your computer. They are interfering with the installation and OneTouch options, and you
need to remove those other drivers and re-install your Xerox
®
scanner. Please see the
documentation that you received with the other scanner for the steps to remove its driver
programs.
Problem
: My computer keeps giving me out of hard drive space error messages.
The minimum requirement of free hard drive space is for the installation of the scanner driver and
basic, low resolution, scanning. High resolution scans result in files that can be over 1 gigabyte in
size. Free up some space on your hard drive for the software to be able to save the scanned
images.
