The drum only rotates in one direction (CW, viewed from the front of the machine).

NOTE:

1) The main motor encoder sends pulses to the main motor control board

(1000 pulses = 360 degrees).

2) The CPU monitors the pulses and controls the drum speed and stop

positions.

3) The drum has two sensors;

• Master eject sensor [D] (master eject position and drum home

position)

• Feed start timing sensor [E]

4) The drum has two stop positions;

• Master eject (drum home) position

• Master feed position (feed start timing sensor + 111 pulses)
