STEP 3 Connecting to a Computer
Connecting the Scanner to the Computer
Turn OFF the Auto Start switch on the rear of the scanner, and use the
supplied USB cable to connect the scanner to the computer.
IMPORTANT
• Take care not to disconnect the USB cable while data is being
transferred between the scanner and computer during scanning.
• The USB connector to which the scanner is connected on your
computer must be one capable of supplying 500 mA of power.
• Do not connect the scanner to the computer before installing the
software.
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.
Using a USB Hub
The scanner cannot be used when it is connected to a computer via a
bus-powered USB hub. A self-powered USB hub can be used, but
operation is not guaranteed.
Auto Start Switch
There is an Auto Start switch at the rear of the scanner for setting
whether to operate the scanner as a storage device.
Depending on the position of the Auto Start switch, the scanner
operates as shown below.
IMPORTANT
• Turn the Auto Start switch ON or OFF before you connect the
scanner to a computer. If it is turned ON or OFF after the scanner is
connected to a computer, the scanner may not operate properly.
• When you use the scanner with the Auto Start switch turned ON, the
computer needs to be started before you connect the scanner to
the computer. If the scanner is connected to a computer that is not
started and the feed tray of the scanner has been opened to turn
ON the power, the computer may not be able to start.

preinstalled in the scanner enables you to perform
scanning on a computer without the scanner driver
installed. (However, you cannot store scanned
images or any other data on the scanner.)
OFF
The scanner is recognized as a scanning device by
the computer. You can connect the scanner to a
computer with the scanner driver installed, and
perform scanning using an application, such as the
