VII. POWER SUPPLY
1.
Outline
When the host machine power switch is turned ON, 24V and 5V power lines are supplied by
the finisher controller PCB.
The 24V power is used to drive solenoids. The 24V power from the finisher controller PCB to
solenoids does not pass through any protective mechanisms (microswitches, or the like).
The 24V power to motors, on the other hand, will not be supplied if any of the three door
switches is open.
The 5V power is used to drive sensors and ICs.

Protective Mechanisms
The 24 VDC power supply used for motors and solenoids is equipped with a circuit breaker
(CB1). The 24V power supply used to drive the feed motor (M1S), alignment motor (M5S), and the
paper positioning plate motor (M4S) is equipped with a fuse designed to blow when an overcurrent
flows.
