This copier uses a dual carbon coated tungsten wire corotron for the drum
charge. The corona wire generates a corona of positive ions when the charge
power pack [A] applies a high voltage.
The output of the charge power pack is determined by the CPU based on the
process control data.
The charge power pack has a leakage sensor. If a leak (short circuit) is
sensed, the output is interrupted.
