In a laser printer, _______ 's functions are to convert AC current into usable energy for the logic circuitry and motors.


The printer's logic circuitry and motors operate on low voltages ranging from +5 VDC to +24 VDC. To provide these voltages, the DC power supply (DCPS) transforms the incoming household current into three specific voltages. It generates +5 VDC and -5 VDC for the logic circuitry and supplies +24 VDC for the paper-transport motors. Additionally, the DCPS powers the cooling fan responsible for maintaining the printer's internal component temperatures.
