Ricoh B064 Service Manual page 635

When the finisher has received the command that changes the number of punch
holes for the job, the punch hole motor [A] turns on until the actuator disk changes
the status of the punch hole switch [B] (until it switches on or off). This indicates
that the cover [C] and the punch cam [D] have moved to one side or the other to
determine which punchers are used.
