8.2 Puncher Unit (option)
8.2.1 Outline
When the host machine is turned on, the puncher unit is supplied by the finisher controller
PCB with 24-V and 5-V power.
The 24-V power is used to drive the motors, while the 5-V power is used by sensors and
the ICs on the punch controller PCB.
The 24-V power to the motors will be cut off when the joint switch (MS2) or the front door
switch (MS1) of the finisher unit is open.
F02-802-01 is a block diagram for the power supply system:

8.2.2 Protective Mechanisms
The 24-V system used to drive the punch motor (M1P) and the horizontal registration mo-
tor (M2P) is equipped with a built-in fuse which melts in the presence of overcurrent.
