摘要： An improved electrophotographic printer is provided in which the voltage applied to the charge roller is automatically adjusted to compensate for its changing characteristics over its life span. A high voltage DC power supply includes an output that is connected to the charge roller, and the input side of this high voltage DC power supply is controlled by a microprocessor of the print engine. The print engine controls the output voltage of the high voltage DC power supply by changing the duty cycle of the pulse-width modulated control signal that is supplied to the input of the high voltage DC power supply. A look-up table contains the correct duty cycle for the pulse-width modulated control signal with respect to the number of prints that have been made. The result of the inspection of the look-up table is used by the microprocessor of the print engine to control the correct duty cycle for the pulse-width modulated signal. Over time, the charge roller characteristics begin to change, and after a predetermined number of prints have been made, the pulse-width modulated control signal has its duty cycle increased by a value that is provided in the look-up table. This increase in the duty cycle is performed several times over the operating life of the charge roller, in order to maintain the effective voltage applied to the photoconductive drum to a nominal value.
摘要翻译：提供了一种改进的电子照相打印机，其中施加到充电辊的电压被自动调整以补偿其寿命期间其变化的特性。高压直流电源包括连接到充电辊的输出，并且该高压直流电源的输入侧由打印引擎的微处理器控制。打印引擎通过改变提供给高压DC电源的输入端的脉冲宽度调制控制信号的占空比来控制高压直流电源的输出电压。查找表包含脉冲宽度调制控制信号相对于已经制作的打印数量的正确占空比。打印引擎的微处理器使用查找表的检查结果来控制脉冲宽度调制信号的正确占空比。随着时间的推移，充电辊特性开始变化，并且在已经进行预定数量的打印之后，脉冲宽度调制控制信号的占空比增加了在查找表中提供的值。占空比的这种增加在充电辊的使用寿命中进行几次，以便将施加到感光鼓的有效电压保持在标称值。

摘要： A shield may be provided over a printer developer roll, adjacent to a doctor blade, to reduce toner dusting and toner accumulations. The shield may slightly conform to the curvature of the developer roll in some embodiments. As a result, toner accumulations on surfaces which the customer must touch may be reduced.
摘要翻译：可以在与刮刀相邻的打印机显影辊上提供屏蔽件，以减少调色剂粉尘和调色剂积聚。在一些实施例中，屏蔽可能略微符合显影辊的曲率。因此，客户必须接触的表面上的调色剂积聚可能会减少。
