4.4.2 SMPS (Switching Mode Power Supply)
This is the power source for the whole system. It is an independent module, so it can be used for common
use. It is mounted at the bottom of the set.
The module contains the SMPS, which supplies the DC power for driving the system, and the AC heater
control, which supplies the power to the Fuser. The SMPS has four outputs (+5V, +12V, +12V, and +24Vs).
There are three kinds of power, 120V exclusive (America), 220V exclusive (Europe), and 220V for China
(nations with unstable power supply).
1) AC Input
- Input rated voltage : AC 220V ~ 240V AC 100~127V
- Input voltage range : AC 198V ~ 264V AC 90V ~ 135V
- Rated frequency : 50/60 Hz
- Frequency range : 47 ~ 63 Hz
- Input voltage : Under 4.0 Arms/2.0 Arms
(The state when lamp is off or rated voltage is input/output)
