    • A capping device (12) for a printhead assembly (10) of a pagewidth drop on demand inkjet printer is formed of spring steel and includes an elastomeric onsert (47) having a series of recesses (56) which create chambers positioned over air inlet and exhaust holes (30) of each printhead module (11) of the assembly. These allow the air to flow from one inlet to the next outlet. When the capping device is moved to its capped position, the airways (32) are sealed off so as to prevent air from drying out and therefore blocking the delicate nozzles (62) of the printheads. Another function of the molding is to cover and clamp against nozzle guards (24) of the assembly to protect against drying out and also to keep foreign particles such as paper dust from entering and damaging the printer nozzles (62).
    • 提供了一种打印头组件,其包括供墨结构,两个油墨通道限定结构和打印头集成电路。 供应结构限定了墨水通道和与通道流体连通的孔。 第一墨水路径结构限定墨水路径形成和位于流体连通的相对侧上的墨水入口开口。 第一墨水路径和供应结构被接合,使得相应的入口开口和孔流体连通。 第二墨水路径结构限定墨水路径形成和位于流体连通的两侧的出口孔。 油墨通道结构被接合,使得路径结构限定曲折的油墨路径。 打印头集成电路具有安装在第二墨水通道结构上的墨水入口,使得每个入口与相应的出口孔流体连通。
