Movement of the Blank Exposure Mechanism

1. When the copier is switched ON, the lens first moves in the direction of enlargement and then
returns to the home position. Next, the lens moves in the direction of reduction for blank
exposure up to a point that corresponds to the cassette size. At the time, the blank solenoid
goes ON, and the blank exposure shutter moves in the direction of the arrow by the force of the
spring.
