No other special precautions are required for replacement of the
optoswitches, as they are mounted at fixed positions.
After replacement of the X, Y, or R movements optoswitches
proceed with the relevant cam adjustment, verifying the centering
of the system using the image quality phantom (see Section C and
Section F of this Service Manual).
If a collimator optoswitch is defective, it is necessary to replace
the optoswitch board PA2: verify then that the three positions of
the collimator (panoramic, transcan and ceph) are correctly
selected by the optoswitches.
