The mirror box is a common source of jams for the Super Program. If the mechanism becomes dirty or sticky, latches may not hold the camera in a charged state or may not release the mirror properly when the shutter is fired. Or particular concern are the rubber dampers meant to reduce vibration. They can degrade and become sticky over time seizing up parts of the mechanism. Disassembling, cleaning parts thoroughly and reassembling can usually restore functionality.
