CHAPTER 2 FUNCTIONS & OPERATION
VI. POWER SUPPLY
1. Outline
The DC power supply PCB of this machine is
capable of handling power input of 100 to 240
VAC.
Fig. 2-601 shows a block diagram of the DC
power supply PCB.
AC power is supplied to the DC power
supply PCB by turning on the power switch.
The 100 to 240 VAC power is converted by a
rectifying bridge to unsmoothed 100 to 240 VUN
and sent to the booster assembly. At the booster
assembly, the power is temporarily raised to 380
VDC and then converted to DC.
A fuse is used in the DC power supply PCB
to protect against over-current situations. + 24
VDC is output from the DC power supply PCB to
the main CPU PCB (MAIN_DCON). The
necessary voltage is generated by the switching
regulator IC and FET on the main CPU PCB.
(Refer to Fig. 2-602)
The DC voltages necessary for the pick-up
control PCB (80_SUB) and document tray control
PCB (10_SUB) are supplied from the main CPU
PCB.
