CHAPTER 2 OPERATIONS
The supplies to the inlet motor (M1), buffer, motor (M2), and stapler shift motor (M10) are sent
to the finisher controller PCB by way of the front cover switch (MSW1) in the form of 24 VZDR; the
other supplies are sent directly from the switching regulator.
c.
5 V Power Supply
It is sent directly by the switching regulator.
Reference:
The output accuracy of each DC power supply is as follows:
36 V:
+11%, -5.5%
24 V:
±5%
5 V:
5.2 ±5%
The above applies when the AC input is 85 to 132 V (100/115V area) or 187 to 264 V
(230V area).

Protective Functions
a.
AC Fuse PCB
The AC fuse PCB is equipped with two fuses (FU731, FU733) which cut off the circuit in
response to an overcurrent. The PCB is also provided with a spare fuse (FU732).
b.
Switching Regulator
The switching regulator is equipped with a fuse (F001) which cuts off the circuit in response to
an overcurrent.
c.
Fuse PCB
The fuse PCB is equipped with the fuses shown in Table 2-803 which blow in response to an
overcurrent; note that these fuses cannot be replaced in the field:
