PAPER TRANSPORTATION II (2)

Solenoid MBF and Gear MBF:

Control the start and stop of the rotation of the
Roll Assembly MBF. When the Solenoid MBF is
actuated, the MBF Gear is unlatched and
engages with the driving gear. The Gear MBF
then begins to rotate, causing the Roll Assembly
MBF to rotate. After one revolution, the Gear
MBF disengage from the driving gear and is
latched by the Solenoid MBF.

Roll Assembly MBF:

Rotates one turn each time the Solenoid MBF is
actuated. The Roll Assembly MBF feeds one
sheet of paper out of the MBF by each rotation.

Sensor No Paper MBF and Actuator Sensor MBF:

Detect when the MBF is out of paper.
