20
Problem: System Alignment was successful, but now I’m getting bad or no body data.
Solution: It is possible that one or more of the sensors have locked up in an unknown state.
1. SHUTDOWN the computer.
2. Disconnect AC power to the computer.
3. Unplug all 20 sensor USB cables from the back of the computer.
4. Reconnect all 20 sensor USB cables.
5. Connect AC power and start the computer.
6. Launch the Scanner software.
Problem: System Alignment failed
Solution: Ensure the Alignment Board is the only thing inside the scanning area, and that nothing is
obstructing the sensors.
Make sure the Alignment Board is vertical and not moving. Lower the Alignment Board
stabilizer foam tube to the floor to steady the object.
If the alignment continues to fail contact

Problem: An error message says the computer is looking for 20 sensors but only sees 19.
Solution: There are several things that can cause this error:
1. A loose USB connection: Check all the USB connections at the computer and at the sensors
and make sure they are secured.
2. A sensor that has gone into an unknown state and needs to be reset: You can reset the
sensors to a known state by shutting down the computer; disconnecting the AC power to
the computer; disconnecting all sensors from the computer and re-connecting all sensors
back into the computer; connect AC power and start the computer.
3. A failed USB port: This can be checked by disconnecting the sensors from one USB card at-a-
time and monitoring the number of sensors in the Device Manager as you do this. You
should be able to determine if a USB card has a bad port if the number of sensors does not
change when you unplug the cable. Move that cable to one of the unused USB ports and see
if the sensor appears on the list again.
4. A failed USB cable: This is not common but is possible. If you have tried the above steps and
the sensor still does not appear in the Device Manager, switch the USB cable with one from
another sensor. If the sensor now appears in the Device Manager, it is probably the cable.
Replace it with a new cable. You can purchase a USB cable locally if you do not have any
spare cables or request one from Size Stream. Contact

5. A failed sensor: If you have tried all the above steps and the sensor does not appear in the
Device Manager, it has probably failed and needs to be replaced. Contact
