摘要： A xerographic marking engine adjusts a charging actuator, such as an AC peak-to-peak voltage or an AC peak-to-peak AC current, based upon toner patch density measurements made using, e.g., a toner patch density sensor. The sensor is used to detect a knee in a toner mass density curve obtained by sweeping an AC peak-to-peak voltage or an AC peak-to-peak current. Once the knee is located, an AC charging actuator peak-to-peak voltage or AC peak-to-peak current is determined that reduces the amount of positive charge that is deposited onto the surface of the photoconductor, thereby extending its life while maintaining acceptable print quality. The described approach may improve photoconductor life without significantly increasing production costs or complexity.

摘要： A xerographic marking engine (100) adjusts a charging actuator (160), such as an AC peak-to-peak voltage or an AC peak-to-peak AC current, based upon toner patch density measurements made using, e.g., a toner patch density sensor (218). The sensor (218) is used to detect a knee in a toner mass density curve obtained by sweeping an AC peak-to-peak voltage or an AC peak-to-peak current. Once the knee is located, an AC charging actuator peak-to-peak voltage or AC peak-to-peak current is determined that reduces the amount of positive charge that is deposited onto the surface of the photoconductor (164), thereby extending its life while maintaining acceptable print quality. The described approach may improve photoconductor life without significantly increasing production costs or complexity.
摘要翻译：基于使用例如调色剂片进行的调色剂片密度测量，静电印迹标记引擎（100）调整充电致动器（160），诸如AC峰峰值电压或AC峰 - 峰电压，密度传感器（218）。传感器（218）用于检测通过扫描AC峰 - 峰电压或AC峰 - 峰电流获得的调色剂质量密度曲线中的膝盖。一旦膝盖被定位，则确定AC充电致动器峰 - 峰电压或AC峰 - 峰电流，其减少沉积在感光体（164）的表面上的正电荷的量，从而延长其寿命同时保持可接受的打印质量。所描述的方法可以提高感光体寿命而不显着增加生产成本或复杂性。

摘要： An electrostatographic printing apparatus comprises a charge receptor (10), and a transfer station for transferring a toner image from the charge receptor (10) to a sheet (S). The sheet passes through a nip formed between the charge receptor (10) and a moving transfer belt (30). Upstream of the nip, the belt (30) forms a shallow angle relative to the charge receptor (10), downstream of the nip, the belt (30) forms a steep angle relative to the charge receptor (10). This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.
