200
What is DCC and what does it do?
The direct current controller (DCC) is responsible for handling and distributing the DC electrical power within the printer components and systems and Routes all the electrical control signals
200
What does the Low Voltage Power Supply (LVPS) do?
The LVPS is responsible for supplying 120 V alternating current (AC) to the fuser, and 5 V DC and 24 V DC to the sensors, motors, fans, and other printer assemblies. The current is fed from the LVPS to the DC controller, which is then responsible for channeling the different voltages to the correct components.
