CHAPTER 6 IMAGE FORMATION SYSTEM
F. Controlling the Post-Cleaning Charging Current
The post-cleaning charging mechanism has the following items of control:
Controlling the static eliminating charge to a constant current level.
Each of the signals is used for the following:
 HVCC (post-cleaning charge ON/OFF control signal)
When '1', the high-voltage output is ready.
 HVCI (post-cleaning charge level control signal)
Controlled to +3 to +11 V; at +11 V or less, the high-voltage output is generated.
