Power Supply

An internal UL recognized switching power module supplies power for the printers. It provides a constant 24VDC output from input voltage in the 90-132 VAC and 180-246 VAC ranges. A power switch turns the power on and off. The 24VDC is applied to the MPCB where it is further regulated and separated into 1.8VDC, 3.3VDC, and 5VDC. The 24V supply is used for: the stepper controller (which advances the paper); the servo controller (which moves the Carriage); and power to fire the inkjets. The 5V and 3.3V supply powers the logic circuits. The 1.8V powers the DSP.
