    • Cleaning apparatus for cleaning debris from orifices in an ink jet printhead nozzle plate includes a structure defining a cleaning cavity between two horizontally contacting rollers where cleaning liquid is loaded, agitated, and dynamically sealed in the cavity trough the rotation of the rollers. A relative movement is also provided between the nozzle plate and the cleaning structure so that the nozzle plate can be positioned above the cleaning cavity with the rotating rollers. The nozzle plate is spaced a small distance from the flow of the cleaning liquid that the cleaning fluid fills this small distance. The flow causes the cleaning fluid to engage the nozzle plate and remove debris from the nozzle plate and orifice nozzles. After the cleaning cycle has ended the cleaning fluid is discarded.
    • 用于清洁喷墨打印头喷嘴板中的孔的碎屑的清洁装置包括在两个水平接触的辊之间限定清洁腔的结构,其中清洁液被装载,搅动并且通过辊的旋转动态密封在空腔中。 在喷嘴板和清洁结构之间还提供相对运动,使得喷嘴板可以利用旋转辊定位在清洁腔的上方。 喷嘴板与清洁液体的流动间隔开一小段距离,清洁液体填充这么小的距离。 流动导致清洁流体接合喷嘴板并且从喷嘴板和喷嘴喷嘴去除碎屑。 在清洁循环结束后,清洗液被丢弃。
