4.4.2 Switching Mode Power Supply

The SMPS is the power source for the entire printer system. The SMPS supplies DC power for driving the printer, and
the AC heater control which supplies power to fuser. The SMPS has two output channels: 3.3 V and +24 V.
1) AC Input
Input Rated voltage: AC 220 V ~ 240 V, AC 120 V ~ AC 220 V (EXP version)
Input Voltage range: AC 198 V ~ 264 V, AC 90 V ~ 135 V, AC 198 V ~ 264 V (EXP version)
Rated Frequency: 50/60 Hz
Frequency range: 47 ~ 63 Hz
Input Current: Under 4.0A RMS/2.0A RMS (When the fuser lamp is off and input / output voltages are in range)
