    • A method for inspecting the liquid discharge condition of a liquid jet recording head, which is structured by assembling a ceiling plate having discharge ports formed on it to discharge liquid, and energy generating means to generate energy for discharging liquid, comprises the steps of forcing liquid to flow out from the discharge ports of the ceiling plate after the discharge ports are processed and formed on the ceiling plate, but before the assembled structure is formed, of observing and measuring the flow out condition of the liquid, and of calculating the discharge angle of the liquid. With the method thus arranged, it is possible to promptly reflect the inspection result of the liquid discharge direction and angle on the processing step accordingly if any deviation thereof is found from the regular value, thus enhancing the production yields significantly.
    • 一种用于检查液体喷射记录头的液体排放状态的方法,其通过组装具有形成在其上的排出口排出液体的顶板和能量产生装置来产生排出液体的能量,包括以下步骤:强制液体 在排气口处理并形成在顶板上之后但在组装结构形成之前,从观察和测量液体的流出状态并计算排出角度从顶板的排出口流出 的液体。 利用如此设置的方法,如果从常规值发现其偏差,则可以在处理步骤中及时反映排液方向和角度的检查结果,从而显着提高生产率。
