3.5 Controlling the Output

The output of the DC bias applied to the transfer charging roller is controlled as follows:
The optimum transfer charging roller bias differs depending on paper size and site environ-
ment; as such, the DC controller is designed to automatically control the output level to suit
the paper size and the site environment in question.
