    • A marking engine forms one or more toned patches and/or images on a photoreceptor transfer device such as a photoreceptor belt or drum, either within or outside a main image area. A sensor illuminates the tones patches and/or images on the photoreceptor transfer device using wavelengths outside the photo response range of the photoreceptor transfer device, thereby allowing reflectance values for each toned patch and/or image to be measured without generating ghost images on the photoreceptor transfer device. The sensor supports collection of measured reflectance values from single-color, mixed-color; and multi-separation image-on-image toned patches and/or images directly from the photoreceptor transfer device at rates as high as one or more times per revolution of the photoreceptor transfer device. The measured reflectance values may be used to generate and/or update color stabilization tone reproduction curves.
    • 标记引擎在主图像区域内或外侧在感光器传送装置(例如感光带或鼓)上形成一个或多个调色片和/或图像。 传感器使用感光体传送装置的光响应范围之外的波长照亮感光体传送装置上的色调和/或图像,从而允许测量每个调色片和/或图像的反射率值,而不在感光体上产生重影图像 传输设备。 传感器支持从单色,混合色彩中收集测量的反射率值; 以及以感光体转印装置的每转一次或多次的速度从感光体转印装置直接进行多重分离的图像上调色片和/或图像。 测量的反射率值可以用于产生和/或更新稳定色调再现曲线。
