    • An imaging apparatus includes a first side frame and a second side frame, the second side frame being spaced apart from the first side frame. A guide rail extends between the first side frame and the second side frame. A guide rod having a first end, a second end and an axis is provided that extends between the first side frame and the second side frame, the guide rod being positioned to be substantially parallel to the guide rail. A printhead carrier that carries a printhead has a slotted portion for slideably engaging the guide rail and has a bearing for slideably engaging the guide rod. A first eccentric bushing assembly is provided for movably mounting the first end of the guide rod to the first side frame. A second eccentric bushing assembly is provided for movably mounting the second end of the guide rod to the second side frame. A gap spacing adjustment mechanism is coupled to at least one of the first eccentric bushing assembly and the second eccentric bushing assembly for effecting a change in position of the guide rod in a direction normal to the guide rod axis so as to adjust a spacing of a gap between the printhead and a print medium.
    • 一种成像装置包括第一侧框架和第二侧框架,第二侧框架与第一侧框架间隔开。 导轨在第一侧框架和第二侧框架之间延伸。 提供具有第一端,第二端和轴的导杆,其在第一侧框架和第二侧框架之间延伸,导杆定位成基本上平行于导轨。 携带打印头的打印头托架具有用于可滑动地接合导轨的开槽部分,并且具有用于可滑动地接合导杆的轴承。 提供第一偏心衬套组件,用于将导杆的第一端可移动地安装到第一侧框架。 第二偏心衬套组件被设置用于将导杆的第二端可移动地安装到第二侧框架上。 间隙间隔调节机构联接到第一偏心衬套组件和第二偏心衬套组件中的至少一个,用于在垂直于导杆轴线的方向上实现导杆的位置变化,从而调节 打印头和打印介质之间的间隙。
