Power Supply
2.7.1
Power Supply Route (Finisher Unit)
0009-2555
When the power of the host machine is turned on, 24 VDC is supplied from the host machine to the finisher controller
PCB through two power supply lines. 24 VDC supplied through one power supply line is used to drive motors and
solenoids. 24 VDC supplied through the other power supply line is converted into 5VDC by the regulator IC (IC102)
on the finisher controller PCB and then used to drive the sensors on the PCB. Furthermore, it is converted into 3.3
VDC by the regulator IC (IC109) on the finisher controller PCB and then used to drive the ICs on the PCB. Both are
also supplied from the finisher controller PCB to the saddle stitcher controller PCB.
If the Puncher unit, which is an optional, is installed, they are supplied to the punch controller PCB as well.
24VDC for specific motor drives is cut off when the front cover switch (MSW101) is open. This is not applied to
the optional puncher unit and some other motors.
A block diagram of power supply is shown below.

The 24 VDC for motor and solenoid drive has a fuse or motor driver with over-current protection function for over-
current protection.
2.7.3
Power Supply Route (Saddle Stitcher Unit)
0009-2557
When the power switch of the host machine is turned on with the door closed, 24 VDC is supplied from the finisher
