When the reverse roller solenoid [A] is turned off, the reverse roller [B]
stops as the stopper [C] locks the clutch gear [D].
However, since the feed roller [E] turn continuously, the master continues to
be fed causing the master to buckle. This buckle is detected by the master
buckle sensor [F]. When the sensor turns on, the main motor turns on at 10
rpm to rotate the drum. The main motor turns off when the sensor turns off.
Therefore, the master is fed by the ON/OFF action of the master buckle sen-
sor.
