∗ The Aperture Unit is supplied by being set in the charge position 
  (initial position), but if this position is disordered when the Aperture 
  Unit is removed, or if the charge position is to be set again, perform

  method at the charge position.

1-15. Aperture Unit Free Position Setting

  accidentally and the charge position is disordered, or if the charge 
  position was shifted during disassembly.

1-14. Aperture Unit Charge Position Setting
1. Check that the Aperture Unit is in a free state.
2. After confirming that the Aperture Unit is in a free state, rotate the 
  gear by 3 turns.

  holes in the gear and the Aperture Unit coincide. This position is the 
 charge

much from a free state.

If the edge of spring is located downward,
rotate the gear in the arrow direction to
search a free position.
∗ In a free position, the edge of spring is
 located upward.

First, check the
