Fixed primary collimator: Panoramic beam horizontal
position
If the X-ray beam is too far to the left or right of the alignment rectangle, it must be centred.
Loosen the two M3x10 ISO 7380 screws that hold the primary collimator plate in position with
the 2mm Allen key and move the plate until the beam is correctly positioned (Fig. 25, 2).
Tighten the screws and recheck the beam. Repeat the above procedure until the beam is cor-
rectly positioned.
Fixed primary collimator: Panoramic beam vertical
position
If the X-ray beam is too low or too high, the vertical position of the beam must be adjusted.
Loosen the three M4x12 DIN 912 screws that hold the vertical adjustment frame in position
with the 3mm Allen key and move the frame until the beam is correctly positioned (Fig. 25, 3).
Tighten the screws and recheck the beam. Repeat the above procedure until the beam is cor-
rectly positioned.
