1.3 Checking and adjusting the sensor head and second
primary collimator mutual position
The sensor head must be in line with the second primary collimator. Check the positions as
follows.
Move the scanning mechanism to center position. For both the sensor head and the second
primary collimator the right corner of the sledge must hit the circle on the digital cephalostat
frame as shown in the figure below.
Figure 7
If the sensor head sledge does not hit the circle on the digital cephalostat frame at the same
time as the second primary collimator sledge, the sensor head position must be adjusted.
To adjust the position loosen the three adjustment screws of the belt wheel with the 4mm
Allen key (Fig. 9, 1 and 2). Lift the belt over the timing belt wheel so that the wheel does not
rotate (Fig. 8) and move the collimator so that the right edge of the sledge hits the circle on
