open when you received the error message.
2 Disconnect the USB cable from the scanner and then reconnect it. (Try to
do a scan to see if the scanner is working now. If not, proceed with the
next step.)

4 Unplug the scanner from the power source.
5 Disconnect the USB cable from the scanner and the computer.
