    • A method by which the target of a toner concentration (TC) sensor can be set up based on the equivalent developability concept without using an expensive patch generator. First, use a black toner area coverage (BTAC) sensor to measure the relative reflectance (RR) of a 100% area coverage developed patch (ROS generated) at a series of development levels (Vem or Vdev) to generate a pseudo development curve and estimate VdO in real-time (VdO is the Vdev level that starts to develop toner onto the photoreceptor belt.) Then, add a nominal delta Vdev to VdO to get the development level (Vdev) needed to generate 100% area coverage gray patch. Finally, using a BTAC sensor to measure the RR level of a 100% area coverage (AC) gray patch, move the target of the TC sensor, and converge the sensor's reading to the sensor's target continuously until the RR level of the gray patch hits the RR target (predefined) within the tolerance range. Thus, the target of the TC sensor is set for the xerographic system automatically.
    • 可以在不使用昂贵的贴片发生器的情况下,基于等效显影性概念设置调色剂浓度(TC)传感器的目标的方法。 首先,使用黑色调色剂区域覆盖(BTAC)传感器来测量在一系列开发水平(V SUB)或V(V)下的100%区域覆盖开发贴片(ROS生成)的相对反射率(RR) )以生成伪显影曲线并且实时地估计V OUT(V OUT)是V >水平,开始在感光带上显影调色剂。)然后,向V DO 添加额定的ΔV以获得显影水平(V < / SUB>)需要生成100%的区域覆盖灰度补丁。 最后,使用BTAC传感器测量100%区域覆盖(AC)灰色块的RR电平,移动TC传感器的目标,并将传感器的读数连续收敛到传感器的目标位置,直到灰色片段的RR电平达到 RR目标(预定义)在公差范围内。 因此,TC传感器的目标将自动设置为静电复印系统。
