4.5 3RD SCANNER DRIVE
To compensate the focusing for reproduction and lens position changes, the
3rd scanner (4th and 5th mirrors) position is changed.
The 3rd scanner drive motor [A] (a stepper motor) changes the 3rd scanner
position through the pinion gears [B] and the rack gear [C].
The 3rd scanner home position sensor [D] detects the 3rd scanner position
for full size mode. The machine keeps track of the 3rd scanner position
based on the number of motor drive pulses.
