    摘要： An ink-jet image forming apparatus. The ink-jet image forming apparatus includes a print head having a plurality of nozzles to eject ink, an ink tank to store the ink, an ink supply passage to supply the ink in the ink tank to the print head, an ink return passage to return the ink in the print head to the ink tank, a regulator mounted in the ink supply passage to regulate ink flow supplied to the print head, a shut-off valve mounted in the ink supply passage, between the ink tank and the regulator, to intercept ink flow supplied to the regulator, and an ink pump mounted in the ink return passage to forcedly flow the ink in the ink return passage. The ink pump is configured to be driven in forward and reverse directions so as to change an ink flow direction. Since the shut-off valve intercepts forcedly the ink flow in the ink supply passage, the ink in the ink tank is prevented from flowing abnormally to the print head and leaking from the print head.

    摘要翻译： 一种喷墨图像形成装置。 喷墨图像形成装置包括具有多个用于喷射墨水的喷嘴的打印头，用于存储墨水的墨水罐，用于将墨水罐中的墨水供应到打印头的墨水供应通道，将墨水返回通道 将打印头中的墨水返回到墨水盒，安装在供墨通道中的调节器以调节供应到打印头的墨水流量，安装在墨水供应通道中的墨水盒和调节器之间的截止阀， 以拦截供应到调节器的墨水流量，以及安装在墨水返回通道中的墨水泵，以迫使墨水返回通道中的墨水流动。 墨水泵被配置为沿正向和反向驱动以改变墨水流动方向。 由于截止阀强制地拦截供墨通道中的墨水流动，所以防止墨水盒中的墨水异常地流到打印头并从打印头泄漏。
