6 Reconnect the USB cable that connects the computer and the scanner.
Make sure that the USB cable is properly connected to the back of the
scanner. The USB symbol on the end of the cable (the connector) should
be facing up. When connected correctly, the USB connector feels slightly
loose. When connected incorrectly, the USB plug feels overly tight.
Try connecting the USB cable to a different USB port on your computer.
If the scanner still fails to initialize, run the Repair utility (Windows computers only)
as described in the Scanner has stopped working properly section.

correctly connected, test the scanner using this procedure.
