Figure 5-3 High Voltage Power Supply Circuit
In response to the instructions from the microprocessor (CPU: IC301)
on the DC controller, this circuit applies the superimposed voltage of
DC voltage and AC voltage to the primary charging roller and
developing cylinder, and a positive or negative DC voltage to the
transfer charging roller.
According to the image density information sent from the Formatter
PCA, this circuit varies the primary DC bias and developing DC bias
to adjust the image density.
