Abstract: Apparatus for providing ink to an ink-jet print head in a print cartridge (14) at substantially constant pressure and for compensating for air within the print cartridge (14). A flexible bag (52) is maintained at atmospheric pressure within the print cartridge (14) and actuates a pressure regulator also within the print cartridge (14). By expanding and contracting, the flexible bag (52) compensates for changes in pressure and temperature that occur while the pressure regulator is shut and that affect air entrapped within the print cartridge (14).
Abstract translation: 用于以基本恒定的压力向打印墨盒（14）中的喷墨打印头提供墨并用于补偿打印墨盒（14）内的空气的装置。 柔性袋（52）保持在打印盒（14）内的大气压力下，并且也在打印盒（14）内也启动压力调节器。 通过膨胀和收缩，柔性袋（52）补偿压力调节器关闭期间发生的压力和温度的变化，并且影响打印盒（14）内的空气。

Abstract: Disclosed is an inkjet printing system (10) including a semipermanent printhead (12) having a fluid input for receiving ink and an injection portion for depositing ink in response to control signals. The printing system also includes a replaceable ink supply (14) configured for providing ink to the printhead that stores an ink volume. The printhead is capable of lasting throughout the life of a plurality of the ink volumes. The printing system includes a fluid accumulator portion in fluid communication with the printhead and replaceable ink supply. The fluid accumulator is adapted to accommodate the air introduced into the printhead during the usage of the ink supplies without purging air from the printhead.
