Troubleshooting
Problem: The scanner won’t scan. What’s wrong? 
Check for one of these possible causes:
• 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. If you are using a UPS battery 
back-up or power strip, try plugging the scanner directly to a wall outlet.
• Did you restart the computer and scanner? If the scanner gets a paper jam, or looses 
connection because of an error, try restarting your computer and power cycling the 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

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 contains thorough instructions for cleaning this part of the scanner.
