    • Provided is a method of controlling a CMOS-implemented control circuit for operating a micro-electromechanical inkjet nozzle arrangement of a printer. The circuit includes a plurality of sequential shift registers, a transfer register, a firing control gate and a drive transistor. The method includes the steps of transferring data from the shift register to the transfer register, latching the data in said transfer register, activating the firing control gate to arrange a heater element of the nozzle arrangement in electrical communication with a current source to facilitate ink ejection via thermal cavitation of ink in the nozzle.
    • 提供了一种控制用于操作打印机的微机电喷墨喷嘴布置的CMOS实现的控制电路的方法。 电路包括多个顺序移位寄存器,传输寄存器,触发控制栅极和驱动晶体管。 该方法包括以下步骤:将数据从移位寄存器传送到传送寄存器,将数据锁存在所述传送寄存器中,激活点火控制门以使喷嘴布置的加热器元件与电流源电连通以便于喷墨 通过喷嘴中的墨水的热空化。

    • An inkjet printer that has at least three ink tanks for storing inks of different color, a printhead cartridge having a printhead with a nozzle face defining an array of nozzles, and a fluid coupling for supplying the printhead with ink from each of the ink tanks. The printer also having a cradle defining a reference surface for engaging a datum point on the printhead cartridge to support the nozzle face at a precise spacing from a media feed path and a latch for securing the printhead cartridge in the cradle, the latch being movable between an open position where access to the cradle is unobstructed, and a closed position where access to the cradle is obstructed. The latch is configured to apply a compressive force urging the datum point on the printhead cartridge into engagement with the reference surface. The printer further including a fluid interface in fluid communication with the ink tanks and a mechanical linkage between the latch and the fluid interface such that the fluid interface is displaced into sealed engagement with the fluid coupling upon moving the latch to the closed position, the fluid interface being displaced in a direction that does affect the compressive force between the datum point and the reference surface.
    • 一种喷墨打印机,其具有至少三个用于存储不同颜色的油墨的墨盒,打印头墨盒具有打印头,该打印头具有限定喷嘴阵列的喷嘴面,以及用于从打印头向每个墨盒提供墨水的流体联接器。 打印机还具有支架,其定义用于接合打印头墨盒上的基准点的基准表面,以便以与介质馈送路径精确的间隔和用于将打印头卡盒固定在托架中的闩锁支撑喷嘴面,该闩锁可在 打开位置,其中通往通道的通路畅通无阻,并且其中阻挡通向通讯座的关闭位置。 闩锁被配置为施加一个压力,该压缩力推动打印头墨盒上的基准点与参考表面接合。 所述打印机还包括与所述墨盒流体连通的流体接口以及所述闩锁和所述流体接口之间的机械连接,使得当将所述闩锁移动到所述关闭位置时,所述流体接口被移位成与所述流体联接器密封接合,所述流体 界面在确实影响基准点和参考表面之间的压缩力的方向上移位。
