Troubleshooting
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. 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 DocuMate 4790
is the selected scanner.
Problem: The scanned images are of poor quality. What do I do?
