Scanner motor: Drives the scanners
Scanner home position sensor: Detects when the scanner is at
home position
The main points are on the slide.
The scanner speed is in the service manual. It depends on the reproduction ratio.
The speed is double the normal speed when returning to home position.
The first scanner contains the exposure lamp, reflectors, the 1st mirror, and the
lamp regulator. The second scanner contains the 2nd and 3rd mirrors.
The regulator is mounted on the scanner to reduce the wiring between the
lamp and the regulator.
The second scanner moves at half the speed of the first scanner. This is to
maintain the focal distance between lens and original.
In this machine, wires are used instead of timing belts. These are more difficult to
replace, but copy quality is better (less jitter).
