Abstract
A xerographic charging device corona current is determined by forming a first signal across a sense resistor in series with the charging device power supply, forming a second signal using a resistive voltage divider network across the power supply, and forming a third signal using a resistor-capacitor charging circuit across the power supply, and then processing the first, second and third signals to form an output signal that is based on the corona current.
