STEP 2: CONNECT THE SCANNER
Your OneTouch 9420 scanner connects to any available USB 1.1 or
USB 2.0 port. Check your computer’s user guide for port locations.
To connect the scanner to a USB 1.1 or USB 2.0 port:
1. Remove all shipping tape from the top and bottom of the scanner.
Slide the locking tab on the bottom to its unlocked position.
2. Make sure that the TPA cable is securely plugged into the Option
port on the back of the scanner.
Note: You do not have to shut off the power to your computer when
connecting the scanner to a USB port.
Note: The locking tab protects the scanner’s scan head by holding it
securely in position. Lock the scanner when transporting it from one
location to another, but remember to unlock it before scanning. The
scanner will not scan when locked.
