Using an Auxiliary Power Supply
Since this scanner is bus-powered, scanning can be performed with a
single USB cable. However, scanning can be performed at a higher
speed if you use the power supply USB cable or an AC adapter (sold
separately).
Connect the power supply USB cable or AC adapter (sold separately)
to the power connector at the rear of the scanner.

Hint
When connected to a USB port that supports USB 3.0, the scanner
operates on 900 mA bus power and is capable of high-speed
scanning. Using the power supply cable in such cases will not
increase the scanning speed.
Although this scanner supports USB 3.0 bus power, USB data
transfer rates remain at USB 2.0 speeds.
