Power Supply Route
0004-4503
When the power of the host machine is turned on, 13VDC and 24VDC are supplied from the host machine to the
Finisher controller PCB. 24VDC is used to drive motors and solenoids, and 13VDC is converted into 5VDC by the
regulator IC (IC107) on the Finisher controller PCB and used to drive the sensors on the PCB. Furthermore, it is
converted into 3.3VDC by the regulator IC (IC108) on the Finisher controller PCB and used to drive the ICs on the
PCB. If the Puncher unit, which is an optional, is installed, they are supplied to the punch controller PCB as well.
Part of 24VDC to drive motors is interrupted when the front cover switch (MS31) is open.
A block diagram of power supply is shown below.
