    • Imaging apparatus and methods of homogenizing ink are described. In one implementation an imaging apparatus includes an ink supply to provide ink to be used in printing, and a printhead to apply the ink during printing. A conduit system couples the ink supply and the printhead in fluid flowing relation. A pump is operably coupled to the conduit system. In operation, the pump causes the ink to circulate between the ink supply and the printhead. A timing device measures an idle-time since the pump was last in operation. A controller receives the idle-time measurement from the timing device, and actuates the pump when a selected idle-time is reached. In another implementation, a method for homogenizing ink includes providing a pump, then automatically actuating the pump to homogenize ink within an ink delivery system each time the ink delivery system has been resting for a selected idle-time.
    • 描述了成像设备和均质墨的方法。 在一个实施方案中,成像设备包括用于提供用于打印的墨水的墨水供应源和在打印期间施加墨水的打印头。 导管系统以流体流动的关系连接墨水供应源和打印头。 泵可操作地联接到管道系统。 在操作中,泵使墨水在墨水供应和打印头之间循环。 定时装置测量泵最后运行时的空闲时间。 控制器从定时装置接收空闲时间测量,并在达到选定的空闲时间时启动泵。 在另一个实施方案中,用于均质化墨水的方法包括提供泵,然后在每次墨水输送系统已经停留在选定的空闲时间时自动致动泵以均匀化墨水输送系统内的墨水。

    • A volumetric fluid dispensing device can include a fluid reservoir having at least one flexible wall and a dispensing reservoir oriented above the fluid reservoir. The dispensing reservoir can have an overflow return fluidly connected to the fluid reservoir such that the dispensing reservoir holds a measured volume of fluid. A reservoir conduit can be fluidly connected to the fluid reservoir and the dispensing reservoir to allow excess fluid to return from the overflow to the fluid reservoir. A dispensing conduit can also be fluidly connected to the dispensing reservoir to allow fluid to exit the dispensing reservoir. A mechanical wall actuator can be operatively associated with the walls for controllably flexing at least a portion of the walls sufficient to force fluid from the fluid reservoir to the dispensing reservoir via the reservoir conduit.
    • 体积流体分配装置可以包括具有至少一个柔性壁和定向在流体储存器上方的分配储存器的流体储存器。 分配储存器可以具有流体连接到流体储存器的溢流回流,使得分配储存器保持测量的流体体积。 储存器导管可以流体地连接到流体储存器和分配储存器,以允许过量的流体从溢流器返回到流体储存器。 分配管道也可以流体地连接到分配储存器,以允许流体离开分配储存器。 机械壁致动器可以与壁可操作地相关联,用于可控地挠曲壁的至少一部分,足以迫使流体经由储存器导管从流体储存器流到分配储存器。
