    • A fluid ejection and scanning system includes a fluid ejection assembly. The assembly includes a first plurality of photosensors, and a first plurality of ejection elements. Each of the ejection elements is configured to cause fluid to be ejected when the ejection element is activated. Each one of the photosensors in the first plurality is coupled to a respective one of the ejection elements for activating the ejection element. A second plurality of photosensors captures image data to generate a digital image of a media. A first light source of the system emits a light beam. A control system scans the light beam across the printhead assembly and selectively illuminates the photosensors in the first plurality, thereby activating the ejection elements coupled to the illuminated photosensors.
    • 流体喷射和扫描系统包括流体喷射组件。 组件包括第一多个光电传感器和第一多个喷射元件。 每个喷射元件构造成当喷射元件被启动时使流体喷射。 第一多个光敏传感器中的每一个耦合到用于激活喷射元件的相应的一个喷射元件。 第二多个光传感器捕获图像数据以产生媒体的数字图像。 系统的第一光源发射光束。 控制系统扫描穿过打印头组件的光束并选择性地照亮第一多个光敏元件,由此激活耦合到照明光电传感器的喷射元件。
