    摘要： A print system for duplex printing a plurality of document page images on a plurality of copy sheets includes means for storing print control information which defines the document images. An ink jet printer prints the page images on copy sheets as they are transported past a print station by a transport arrangement defining a closed sheet path. The sheet path is of sufficient length such that a number of copy sheets are transported simultaneously therethrough. A copy sheet inverter receives copy sheets sequentially from the sheet path after the sheets are printed on their first sides and returns them to the sheet path in an inverted orientation prior to printing on the second sides of the copy sheets.

    摘要： An ink jet fluid system and process of startup and shutdown is provided which includes a print head having a fluid manifold and at least one orifice for forming a jet drop printing stream. Inlet and outlet valves are connected to inlet and outlet openings of the print head. During shutdown, fluid is continuously circulated around the print head through a bypass line while the outlet of the print head is connected to a source of reduced pressure to prevent fluid from flowing through the orifice. At startup, the inlet and outlet valves are actuated to provide a continuous flow of fluid under pressure to the print head. In another embodiment of the invention, a fluid system is provided for a multiple print head device and provides for independent control of the fluid pressure in each print head.

    摘要翻译： 提供一种喷墨流体系统和启动和关闭的过程，其包括具有流体歧管的打印头和用于形成喷射液滴印刷流的至少一个孔口。 入口和出口阀连接到打印头的入口和出口。 在关闭期间，流体通过旁路管线在打印头周围连续循环，同时打印头的出口连接到减压源以防止流体流过孔口。 在启动时，进口和出口阀被致动以在压力下向印刷头提供连续的流体流。 在本发明的另一个实施例中，为多打印头装置提供流体系统，并提供对每个打印头中的流体压力的独立控制。
