Shutter Unit Assembly
The focal-plane shutter consists of multiple carbon-fiber or polymer blades driven by high-tension springs and electromagnetic actuators. A 'stuck closed' state typically signifies a mechanical fracture in the curtain linkage or a failure of the shutter charge motor to cycle the blades back to the open position. Replacing the complete assembly ensures the physical integrity of the curtains and the precise timing of the solenoid-driven exposure sequence.
