Typically this error results from one of three things:

  • The area specified causes the body of the probe to hit the side rails of the Scanning Sled.  Make sure that the scan area specified does not include any vertical parts of the sled and/or center the object on the scanning sled.
  • There is a high area in the scan object that impacts the body of the probe before the probe tip.
  • The probe malfunctions and gets stuck in the Closed position during scanning causing it to stall against the scan object of the sled floor.  Check the functionality of the probe using the above procedure.
