    • A single pass ink jet printer includes a plurality of ink jet modules arranged in adjacent rows extending across the width of the surface of an object which is moved with respect to the printer. The modules are mounted on and joined to a manifold which is mounted in a support frame. Ink is supplied to the manifold through an opening in the frame and the manifold distributes the ink to corresponding openings in the ink jet modules where it is directed to arrays of ink pressure chambers and to an outlet which communicates with a corresponding return passage in the manifold leading back to the ink supply. As a result, ink is circulated continuously through all of the ink jet modules, thereby maintaining pigment in suspension in a pigmented ink. An ink supply is removably connected to the printhead through quick-disconnect couplings and, to prevent contamination of the ink in the printhead, filters are provided in the ink supply and at the inlet to the printhead. An additional filter, designed to trap only those particles which would block the orifices in the orifice plate, is positioned between the ink jet modules and the orifice plate.
    • 单通道喷墨打印机包括布置在相邻行中的多个喷墨模块,该喷墨模块延伸穿过相对于打印机移动的物体表面的宽度。 模块安装在并连接到安装在支撑框架中的歧管。 墨水通过框架中的开口供应到歧管,并且歧管将墨水分配到喷墨模块中的相应开口,其中它被引导到墨压力室的阵列以及与歧管中的相应返回通道连通的出口 导致墨水供应。 结果,油墨通过所有喷墨模块连续循环,从而将颜料悬浮在着色油墨中。 墨水供应通过快速断开的联接器可拆卸地连接到打印头,并且为了防止打印头中的墨水被污染,在墨水供应器和打印头的入口处提供过滤器。 设计成仅捕获那些阻挡孔板中的孔的颗粒的另外的过滤器位于喷墨模块和孔板之间。
