The Fan removes heat from the printer to prevent overheating.
The Power Switch turns the printer AC Power Supply On/Off.
Two types of LVPS are available: 100/120V and 230V. The LVPS supplies AC power
from the power source to the Fuser Heater; the LVPS also generates and supplies
stable low-voltage DC power used for the logic circuits. The LVPS contains a control
circuit for the Fuser heater, in addition to the power circuit.
LVPS Over-Current Protection Circuit
This circuit stops all outputs if the power supply voltage 3.3 VDC, 5 VDC, or 24 VDC
is shorted. After short is repaired, cycle main power to reset the circuit.
