Figure 3-520 shows the construction of the primary charging assembly. The charge current for the pri-
mary corona wire and the pre-primary corona wire and the grid bias is controlled by the control signal from
the DC controller. The change current for the primary corona wire is constant, and the grid bias is varied
to control the drum surface potential.
