B. Operation
1. Switching the AC Component of the Developing Bias ON/OFF
The square wave generator operates continuously when the copier is switched ON.
a) When ACBON=1
AC bias switch circuit goes ON.
Output from the square wave generator is cut off.
As a result, AC bias is not supplied to the developing cylinder.
b) When ACBON=0
The AC bias switch circuit goes OFF.
As a result, the output of the square wave oscillator goes to the T1 drive circuit. This causes the
AC high-voltage transformer to generate a 1300V AC bias, which is supplied to the developing
cylinder.
Also, the output of the AC high-voltage transformer is rectified and supplied to the static
charge eliminator (approx. 3.2 kV).
