4 Power Supply
The following is an outline of the power supply system.
The DADF’s power supply receives from the copier two types of 24 V; one (input to J4-1)
is supplied to each load by way of a fuse (FU1), while the other (input to J1-6) is supplied to
the sensors and the ADF controller PCB after conversion into 5 V by a regulator (Q28) and
into 5.8 V by another regulator (Q65).
The fuse (FU2) operates to cut off the power for protection in the event an overcurrent
flows into the circuit.
