Scanner has stopped working correctly

If the scanner stops scanning, follow these steps. After each step, start a scan to see if
the scanner is working. If the problem persists, proceed with the next step.

A cable might be loose. Ensure that both the USB cable and power supply are properly
connected.
Use the cable that was included with the scanner. Another USB cable might not be
compatible with the scanner.
