Abstract: In one example, a printhead structure includes: a first layer; an array of openings in the first layer to form printing fluid ejection chambers; a second layer on the first layer; an array of orifices through the second layer, each orifice located adjacent to one of the openings in the first layer; a groove in the first layer spanning substantially a full length of the array of openings; and multiple holes through the second layer to the groove in the first layer.
Abstract translation: 在一个示例中,打印头结构包括:第一层; 第一层中的开口阵列以形成印刷液体喷射室; 第一层上的第二层; 通过第二层的孔的阵列,每个孔邻近第一层中的一个开口定位; 所述第一层中的凹槽基本上跨越所述开口阵列的整个长度; 以及穿过第二层的多个孔到第一层中的凹槽。
