The 4th Mirror is moved to vary the conjugate distance for a particular zoom ratio by driving
the rack-and-pinion gears at the front and rear ends of the mirror using the Mirror Motor
(stepping motor). The Levers of the Holder to which the Mirror is mounted slide along a
tilted rail to change the Mirror angle. This ensures that the light strikes the surface of the PC
Drum in the direction of the normal, thereby preventing resolution from being degraded.
Mirror Reference Position Sensor is used to control the position of the 4th Mirror. It ensures
that the Mirror is located at the home position when the copier is turned ON.
