2.8.1 Power Supply
The following is a diagram of the power supply system of the machine.
The machine is supplied with 2 types of power by the host machine 24 V and 13 V. The 24-
V power is mainly used to drive loads (motor, clutch, solenoid), while the 13-V power is
converted into 5 V by IC10 (DC-DC converter) for use by sensors and the ADF controller
PCB.
Unlike other models, the machine will remain supplied with power even when its feeder
cover is opened.
