If the scanner does not turn on or if it turns off unexpectedly,
try these solutions:
- Make sure the AC adapter is securely connected to the scanner
and to a working electrical outlet.
- If the scanner turns off unexpectedly, you may need to adjust
the Power Off Timer setting.
- Make sure the USB cable is securely connected to the
computer.
- Connect the scanner directly to the computer. The scanner may
not work properly when connected through a USB hub.
- Use the USB cable that came with the scanner.
- Use a USB 3.0 (SuperSpeed) port. You cannot use a USB 2.0 or
USB 1.1 port to operate the scanner on a USB power supply.
