B. Operation
When the power switch (SW2) is turned ON with the main power switch (SW1) ON, the DC power source /1
(DCPS1) supplies the 24V DC power source system for the drive of various types of load in addition to the
power source systems that have been supplied so far. And also, it also supplies the AC power source to the fus-
ing heater lamp /1 (L2), /2 (L3), and /3 (L4) when the main relay (RL1) turns on. In this manner, each of the
boards are supplied with the power source to start the initial operation of the main body.
