Xerox W130 Scanner
• 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
selected as the scanner.
Problem: The scanned images are of poor quality. What do I do?
There are various reasons why the scanned image is of poor quality. The original document may
not be of good quality or the scanner glass may be dirty.
• Try cleaning the scanner. The scanner glass is where the image is captured as the page is
pulled through the scanner. Lift up on the exit release, under the input tray, to open the
scanner. There is glass in the body of the scanner and underneath the lid. Take a soft cloth
and wipe across both pieces of glass. The section "Cleaning the Scanner Glass and
Background Plates" on page 6-7 contains thorough instructions for cleaning this part of 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 6-19 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 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.
