Typically, a xerographic copier has four corona devices, two DC corotrons and two

AC corotrons. In earlier machines, each is supplied from its own supply and where

appropriate, each is provided with an individual control system.

In the arrangement of the drawing, four similar corona devices 1, 2, 3, 4 are arranged to be supplied from a single supply and a feed~-backcontrol loop 5 is

arranged to monitor the output of one of the corona devices (1) and to control the single supply to maintain the output constant and hence, maintain constant the output of all the corona devices.
