2.3.5 Offset Motor Control

The offset motor (M4) is a 4-phase stepping motor. The offset roller is controlled by
changing the rotation direction of the offset motor. The motor driver changes the order and
frequencies of the pulse signals (A, A*, B, B*) output in response to the signal from the
CPU, thus controlling the rotation direction and speed of the offset motor (M4).
