    • A fluid ejection head (18) is disclosed, wherein the fluid ejection head (18) includes an orifice layer (38) disposed on top of a substrate layer (34). The fluid ejection head (18) includes a first group of fluid ejection orifices (22a) and a second group of fluid ejection orifices (22b) formed in the fluid ejection head (18), wherein the first group of fluid ejection orifices (22a) and the second group of fluid ejection orifices (22b) are configured to eject two different fluids, and an elongate channel (32a) formed in the fluid ejection head (18), wherein the channel (32a) is positioned between the first group of fluid ejection orifices (22a) and the second group of fluid ejection orifices (22b) in such a location as to inhibit cross-contamination of fluids ejected from the first group of fluid ejection orifices (22a) and second group of fluid ejection orifices (22b).
    • 公开了一种流体喷射头(18),其中流体喷射头(18)包括设置在基底层(34)的顶部上的孔口层(38)。 流体喷射头(18)包括形成在流体喷射头(18)中的第一组流体喷射孔(22a)和第二组流体喷射孔(22b),其中第一组流体喷射孔(22a) 和第二组流体喷射孔(22b)构造成喷射两种不同的流体,以及形成在流体喷射头(18)中的细长通道(32a),其中通道(32a)位于第一组流体 (22a)和第二组流体喷射孔(22b)喷射的流体的交叉污染的位置上的喷射孔(22a)和第二组流体喷射孔(22b)
