    • An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member. The cartridge may also include an ink level sensing system that utilizes an optical sensing system to detect movement or position of the moveable plate to determine a remaining ink volume. In addition, the cartridge includes a standpipe that places the ink reservoir in fluid communication with printhead and has a longitudinal axis that is disposed at an acute angle relative to the printhead, so that gas bubbles at the printhead may travel toward the reservoir in a horizontal or vertical printing position.
    • 一种用于存储用于印刷的油墨的用于喷墨墨盒的油墨容纳系统,包括刚性盆构件和刚性可移动板。 柔性膜固定在盆状构件的表面和板的表面上,从而在盆形构件,板和柔性膜中形成油墨储存器。 弹簧偏压机构设置在盆体和板之间,用于将板偏离盆状构件,在油墨储存器内产生负压,并且盆构件相对于板的运动保持静止。 盆状构件具有碗状构造,并且弹簧位于储存器内,使得当墨水储存器由于墨水耗尽而塌陷时,柔性膜和可移动板基本上与盆形构件的表面齐平。 墨盒还可以包括墨水量感测系统,其利用光学感测系统来检测可移动板的运动或位置以确定剩余墨水体积。 此外,墨盒包括立管,其使墨水储存器与打印头流体连通,并且具有相对于打印头以锐角设置的纵向轴线,使得打印头处的气泡可以以水平方向朝向储存器行进 或垂直打印位置。
