E. Controlling the External/Internal Static Eliminating Current
The external/internal static eliminating control mechanism has the following items of control:
1. Controlling the static eliminating current to a specific level.
2. Turning on/off the high-voltage output.
Each of the signals is used for the following:
 HVIOC (external/internal static eliminating current AC component ON/OFF control
When '1', the static eliminating current AC component output is ready.
 HVIDCC (internal static eliminating current DC component ON/OF control signal)
When '1', the static eliminating current DC component output is ready.
 HVIDCI (internal static eliminating current DC component level control signal)
Controlled to +3 to +11 V; at +11 V, the high-voltage output is generated.
For related error codes, see D. "Controlling the Separation Charging Current."
