A hook on the Pick grabs the just-exposed film frame and pulls it into the
developer rollers which are Motor-driven. These rollers break the developer pod
and spread reagent throughout the frame. The Pick also pulls one of the Counter
Wheel ratchets forward and the Counter indexes from 10 to 9.
As the Timing Gear continues its rotation, the cam on its face loses contact with
EOC/S9. As a result, EOC/S9 opens and turns the Motor off. The Motor then
coasts and the Timing Gear returns to its starting position.
With Motor power turned off, the Strobe charging circuit then completes the
process of charging the Strobe capacitor.
