When the actuator [A] is pressed down by the original, the 2nd original
sensor [B] is activated and the original transport motor [C] starts rotating.
The rotation of the original transport motor is transmitted to belts [D] and [E]
to turn the lower first original transport roller and lower second original
transport roller. At the same time, both the upper original transport rollers
[F] contact the first and second lower original transport rollers due to
pressure from the springs [G]. The rollers rotate and the original is fed.
When the actuator [H] is pressed down by the original, the original
registration sensor [I] is activated and the original transport motor stops.
When the Master Making key is pressed, the original transport motor rotates
to read the original after the master eject process is finished.
The distance between the sensors is 50 millimeters. If the original
registration sensor is not activated within five seconds, "A" and
indications blink.
