    • An ink jet device includes a print head, an ink tank containing ink therein, a first motor, a second motor, and a control unit. The ink tank is connected with the print head and configured for supplying ink to the print head. The ink contained in the ink tank exerting a static hydraulic pressure onto the print head. The first motor is configured for driving the print head to move in a direction selected from the group consisting of a vertical direction, a horizontal direction, and a combination thereof. The second motor is configured for substantially simultaneously driving the ink tank to move in response to vertical movement of the print head so as to maintain the static hydraulic pressure that the ink exerts on the print head.
    • 一种喷墨装置包括打印头,其中包含墨水的墨盒,第一马达,第二马达和控制单元。 墨水盒与打印头连接并且被配置为向打印头供墨。 容纳在墨水罐中的油墨在打印头上施加静态液压。 第一电动机构造成用于驱动打印头沿从垂直方向,水平方向及其组合组成的组中选择的方向移动。 第二马达被配置为基本上同时驱动墨盒以响应于打印头的垂直运动而移动,以便保持墨施加在打印头上的静态液压。
