finished the start up process. As seen in the figure, the control buttons are
assigned to the corresponding command that is displayed closest to the
physical location of the button.
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.
