摘要： A printer using a line-type ink jet recording head. The line-type head has pressure producing chambers formed by dividing nozzle openings extending in a recording paper width direction with vertical side walls and upper and lower ink flow paths which communicate with each other through the pressure producing chambers and extend in a horizontal direction. Each ink flow path has an inlet for replenishing ink and an outlet for discharging the ink. A plurality of pressure producing elements are provided for applying varied pressures to the pressure producing chambers for jetting ink droplets. A sealing member selectively seals the nozzle openings by abutting on the nozzle openings when the recording head has been evacuated to a predetermined position. An ink tank is connected to the inlets and the outlets through pipes, and an ink stream producing device is arranged in the pipes, for producing streams causing the ink to flow from the ink tank to the lower ink flow path and then to the upper ink flow path through the pressure producing chambers.
摘要翻译：一种使用线型喷墨记录头的打印机。线型头部具有通过将沿记录纸宽度方向延伸的喷嘴开口与垂直侧壁分开而形成的压力产生室，以及通过压力产生室彼此连通并沿水平方向延伸的上下油墨流动路径。每个油墨流动路径具有用于补充油墨的入口和用于排出油墨的出口。提供了多个压力产生元件，用于向喷射墨滴的压力产生室施加不同的压力。当记录头已被抽空到预定位置时，密封构件通过邻接在喷嘴开口上选择性地密封喷嘴开口。墨水罐通过管道连接到入口和出口，并且墨水流生成装置布置在管道中，用于产生使墨水从墨水罐流到下部墨水流动路径，然后到达上部墨水的流通过压力产生室的流动路径。
