Thescannerisdrivenbythescannermotor(M2).
The scanner motor changes its direction of rotation
to move the scanner forward and in reverse. When
the scanner moves forward, the motor speed is
changed to suit the specified reproduction ratio;
when the scanner mover in reverse, however, its
speed is constant regardless of the reproduction
ratio (3.5 times as fast as when moving forward).
The distance over which the scanner moves
varies according to the length of the copy paper and
the reproduction ratio.
