2.2.3 Delivery to the No. 3 Delivery Slot
0007-6138
The following shows the sequence of operation used to discharge paper to the No. 3 delivery slot:
1) Paper arrives from the delivery slot of the host machine. A specific period of time after the leading edge of the
paper reaches the fixing outlet sensor (PS13), the No. 2 delivery motor (M1) and the No. 3 delivery motor (M2)
starts to rotate.

2) When the paper moves past the reversal sensor (PS4A) and its trailing edge reaches a specific point in front of the
reversing roller, the No. 3 delivery motor (M2) stops once and then starts again to rotate in reverse direction after
a specific period of time. At the same time, the No. 3 delivery solenoid (SL3) goes on so that the paper moves past
the No. 3 delivery sensor (PS5A) to reach the No. 3 delivery slot.
