3.2 Connecting the EzScan
To install and connect the EzScan Scanner:
1. Place the docking base on a flat, stable surface and place the EzScan
handpiece securely on the base.
2. Connect the AC/DC power adapter cable to the docking base (the connector
socket is located underneath thebase of the scanner).
3. Connect the provided USB 3.0 cable to the docking base (the connector
socket is located underneath the base of the scanner).
4. Connect the other end of the USB 3.0 cable to the computer.
WARNING: Using a USB cable other than the one provided may
result in system malfunction or reduced performance.
WARNING: Make sure you use the 5.0V 4A power adapter
provided. Failure to do so may result in damage to the scanning
device.

Page 15
5. Connect the adapter block provided to a power outlet.
IMPORTANT: When using a desktop computer, it is strongly
recommended to plug the USB cable to a USB port located at the
back of the computer; not doing so may result in system
malfunction or reduced performance.
DO NOT plug the USB cable into an intermediate hub.
WARNING: Unsuitable installation sites:
•Locations with excessive humidity or dust
•Locations subject to high temperature
•Locations subject to shaking or vibration
•Locations exposed to considerable electrical or magnetic
noise, or other forms of electromagnetic energy
IMPORTANT: If using a laptop computer, make sure the power
supply is connected to a power outlet and not running on battery
power. Failure to do so will mean that the scanner will not have
sufficient power to produce images.
On laptop computers, battery settings in Windows should be
configured to high performance mode only, with no battery
saving option (Settings/System/Battery).
IMPORTANT: Make sure to use a USB port that is compatible
with USB 3.0 (SuperSpeed), usually indicated by this symbol:
not doing so may result system malfunction or reduced
