This may occur after Windows goes into power saving mode to
“hibernate” the computer into a low power state. When you move your
mouse or type on the keyboard it “wakes” the computer back up and
restores full power to the system. This power fluctuation during the
computer’s hibernating period may sometimes cause the scanner to lose
communication to the computer.
Problem: The USB cable was unplugged while scanning,
now the scanner won’t work. What should I do?
Simply turn off the scanner power then turn it back on again. This will
reset the scanner and make it available for scanning.
