It is the power source for the whole system. It is an independent module so it is possible to use for common use. It is
mounted at the bottom of the set.
It consists of the SMPS part, which supplies the DC power for driving the system, and the AC heater control part, which
supplies the power for fuser. SMPS has three outputting channels (3.3V, 5V and +24V).
There are three kinds of power, 120V exclusive (America), 220V exclusive (Europe), and 220V for china (nations with insta-
ble power supply).
