ˆ
The main points are on the slide.
ˆ
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.
ˆ
The first scanner contains the exposure lamp, reflectors, the 1st mirror, and the
lamp regulator. The second scanner contains the 2nd and 3rd mirrors.
¾
The regulator is mounted on the scanner to reduce the wiring between the
lamp and the regulator.
ˆ
The second scanner moves at half the speed of the first scanner. This is to
maintain the focal distance between lens and original.
ˆ
In this machine, wires are used instead of timing belts. These are more difficult to
replace, but copy quality is better (less jitter).
