Power Supply - Canon DU7-1101-000 Service Manual

IV . POWER SUPPLY
Figure 2-401 is a diagram of the machine's power supply system.
The machine is supplied with two channels of 24 V power: one (J4-1 input) is sent to loads
through a fuse (FU1), while the other (J1-6 input) is sent to sensors and the ADF controller PCB after
conversion by a regulator (Q28) to 5 V power.
The fuse (FU1) is used to cut the line to protect the circuit in response to overcurrent.
