In an electrostatographic development system wherein toner is conveyed from a donor member over a development gap to a charge receptor by a development field in the development gap, a method including the step of: monitoring at least a first parameter of the system to detect an arcing condition within the development gap; and if an arcing condition is detected, tuning a duty cycle to avoid the arcing condition.

Dynamic duty cycle for increased latitude

A printing machine having multiple distributed high voltage power supplies is disclosed. The printing machine comprises a print engine having a plurality of high voltage electrical printing machine components. A housing supports at least one of the high voltage power supplies. A receptacle mounted on the housing receives an external connector from one of the machine components. The receptacle is fixed on the housing and is not detachable. A contact located inside the receptacle electrically connects circuitry from the power supply to the external connector. A second contact on the housing electrically connects circuitry from the power supply to a second external connector on the machine component.

Apparatus for applying a high voltage electrical point of load contact

A charging device for producing a voltage potential on a photoconductive member including a corona generator for charging a portion of the image receptor to a substantially uniform potential; a corona generating potential source electrically connected to the corona generator; a sensor for determining the potential on the image receptor; and a microprocessor including an analog to digital converter interconnected to the corona generating potential source; the sensor; and the controller for regulation of the potential on the image receptor.
