Xerographic process control using periodic electrostatic set up to automatically adjust charging potential

摘要

The method comprises initiating a first number of charge and erase photoreceptor cycles, stepping the voltage on the charging grid to obtain a predetermined reading on the sensor, providing signals from the sensor in response to developing a series of test patches on the photoreceptor, adjusting the charging grid in response to the signals, initiating a second number of charge and erase photoreceptor cycles to measure cycle down change in photoreceptor voltage, and determining a short term photoreceptor rest recovery factor. The step of determining a short term photoreceptor rest recovery factor includes the steps of inactivating the charging grid for a given time and immediately activating the charging grid to obtain a signal from the sensor.
