Charge Of Drum - KIP 9000 Service Manual

Charge of Drum

The Image Corona takes negative discharging, and the Drum surface is charged negatively with
-XV evenly by this process. The Drum surface charged with -XV corresponds to the white area of
the printed image pattern.
The value of surface potential "-XV" is not constant. The Auto SP Control automatically changes
the surface potential to the most appropriate level according to the information from Surface
Potential Sensor and Temperature Sensor. (Refer to [3.4.2 Auto SP Control] on page 3-26 for
more detail.)
