9.2 Checking the head support position
Press the ceph mode selection key to enter the ceph mode if you are not already in it. The rotat-
ing unit and cassette carriage will move automatically to the correct position for taking cephalom-
etric exposures. Collimator number 4 will be automatically selected.
Remove the tube head covers and cassette carriage covers (see sections “Tube head covers” on
page H-1, “Secondary slot cover” on page H-1 and “Cassette carriage back cover” on page H-1).
Place the ceph head support alignment tools in the ear post holders as far as they go (Fig. 36, 1).
Rotate the head support to the 90° position.
Look through the opening on the cephalostat cassette holder and the opening on the head sup-
port alignment tools. The fourth primary slot is seen symmetrically if the adjustment is correct
(Fig. 36, 2).
Figure 36
If the fourth primary slot is not seen symmetrically, the head support requires readjustment. See
instruction given in section “Head support adjustment” on page D-35.
