摘要： Xerographic photoreceptor life is improved while maintaining output print quality by adjusting the AC charging actuator of a xerographic machine to a point at which photoconductor life is optimized while maintaining output print quality. Where the actuator is voltage, the actuator is set a predetermined amount above the knee voltage of the photoreceptor surface potential versus peak-to-peak voltage curve, which is determined during operation of the machine. Instead of determining the knee voltage, calibration sheets can be generated for various values of the actuator, the best sheet with the least possible actuator value is selected, and the AC charging actuator is set to the value corresponding to the best sheet. The sheets can be evaluated by a user, or an optical array sensor can be used to scan the sheets so that the controller can compare the sheets to stored criteria to automatically select the best sheet and set the actuator. Alternatively, the optical array sensor can scan calibration images directly from the intermediate transfer belt or other image bearing member, thus eliminating the use of paper for calibration.
摘要翻译：通过将静电复印机的AC充电致动器调整到优化光电导体寿命的时间点，同时保持输出打印质量，可以提高静电感光效果，同时保持输出打印质量。在致动器是电压的情况下，将致动器设定在高于感光体表面电位的拐点电压与在峰值到峰值电压曲线之间的预定量，这是在机器操作期间确定的。代替确定拐点电压，可以为执行器的各种值生成校准页，选择具有尽可能小的执行器值的最佳板，并将AC充电致动器设置为对应于最佳板的值。纸张可以由用户评估，或者可以使用光学阵列传感器来扫描纸张，使得控制器可以将纸张与存储的标准进行比较以自动选择最佳纸张并设置致动器。或者，光学阵列传感器可以直接从中间转印带或其他图像承载部件扫描校准图像，从而消除使用纸进行校准。
