Troubleshooting
Status Light Troubleshooting
A blue or green status light indicates the normal state of the scanner.
Normal Operation
• Blinking blue or green: indicates the scanner is waking up from
power saving and preparing to scan.
• Steady blue or green: indicates the scanner is ready to scan.
Errors
If your scanner experiences hardware problems, the status light blinks
red. Below are some troubleshooting options you can try if you see a
flashing red light.
• Open the scanner and make sure there is no paper jammed in the
ADF. Make sure the cover is fully closed before proceeding.
• Turn off the scanner, restart the computer, then turn the scanner back
on after Windows has finished loading.
• Make sure the USB cable is plugged into the computer and the
scanner.
If you are using a USB hub, try plugging the USB cable directly into
the back of the computer.
If the cable is already plugged into the computer, try plugging it into a
different USB port.
Try a different USB cable.
The USB cable should be no longer than 6 feet (182 cm). If the USB
cable is longer than 6 feet, there will be communication problems
between the scanner and the computer.
• Make sure the power cord is plugged in.
If you are using a UPS battery back-up, surge protector or power
strip, try plugging the scanner directly into the wall. Sometimes the
power fluctuation in these devices can cause communication
problems. If the problem persists, order a replacement power supply
from Xerox.
• The ADF pad may not be fully seated in the scanner body. Open the
scanner, press down on the ADF pad and make sure it snaps into
place.
