Abstract
A method and apparatus for achieving optimum noise control of multiple coronode wires in a copier/printer involves optimizing phase relationships of the voltage on the wires in such a way so as to steer the maximum part of the noise distribution profile in the direction best suited for absorption or dissipation. In a two corotron charging system, the coronodes are preferably charged to where the phase angle, charge frequency and spacing between wires are optimized. If desired, a sound absorption material could be added to the charging system.
