Power Supply
Power Supply Route
The 24V are supplied to the buffer pass controller PCB through the buffer pass relay PCB and the buffer pass power supply PCB
in the buffer pass unit when the host machine is turned ON. The 24V is supplied from the buffer pass unit to the finisher controller
PCB.
The 24V is converted into 5V and 3.3V by the regulator IC on the finisher controller PCB. The 24V is used to drive the motors
and clutches and fan and the 5V is used to drive the sensors and switches and the 3.3V is used to drive the logic. The 24V is
shut down when the opening of the front cover or swing guide is detected by the front cover switch (SW101) or swing guide safety
switch (SW102).
The 24V is converted into 5VDC by the regulator IC on the saddle stitcher controller PCB to drive sensors. It is also converted
into 3.3VDC by the regulator IC on the saddle stitcher controller PCB to drive ICs on the PCB.

Protection Function
The 24V circuits (used to drive the motors and clutches and fan) are provided with the fuses or the motor drivers with an overcurrent
protective function to provide protection from the over current.
The power input circuit of each controller PCB is also provided with a fuse which is blown when an excessive current flows.
