Slide 252
Drive
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 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, and the 1st mirror. The
second scanner contains the 2nd and 3rd mirrors.
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).
