摘要： A sheet stacking apparatus for receiving sheets from a printing or copying machine includes guide structure for directing output sheets onto an elevator platform and a selectively rotatable shaft having paddle arms disposed at a 108.degree. interval. The shaft rotation is controlled so that the arms guide a sheet during stacker input and then rotates 360.degree. to positively clear the sheet trail edge from the stacker input path.

摘要： The present invention constitutes in an ink jet printing apparatus, an improved ink replenishment system. An ink supply housing of the improved ink replenishment system includes a pair of opposed side walls having a plurality of attachments spaced in respective opposing vertical columns and detachable detents coupled to one of the attachments. An attachable ink supply conduit is associated an associated ink supply module includes a container of ink having an ink egress constructed to attach to the conduit, and a housing having bottom and side wall members supporting the container. The side walls have a vertical edge with a plurality of removable sections located in spaced relations corresponding to the column spacing of the attachments and sized to correspond to the detents. Only an ink supply module having proper sections removed can be moved into the housing to an extent sufficient for its egress to connect to the supply conduit.

摘要： In an ink jet printer having a printhead and a printhead docking station, an improvement is provided in installation and retention of the printhead in the printhead docking station. Straight line travel of the printhead relative to the printhead docking station is ensured using guide posts or other guiding mechanisms. Non-abrupt actuation, such as a screw drive actuator is used to translate the printhead relative to the docking station. The screw drive actuator is oriented at near right angles to the direction of translation of the printhead relative to the printhead docking station. The printhead and the printhead docking station are then aligned so that electrical and fluid connections can be made concurrently. During the installation, a consistent insertion force, such as a spring loaded toggle mechanism, is applied to the printhead, regardless of part tolerances.
摘要翻译：在具有打印头和打印头对接站的喷墨打印机中，提供了在打印头对接站中安装和保持打印头的改进。使用引导柱或其它引导机构确保打印头相对于打印头对接站的直线行程。使用诸如螺旋驱动致动器的非突然致动器来相对于对接站平移打印头。螺杆驱动致动器定向成与打印头相对于打印头对接站的平移方向成直角。然后对准打印头和打印头对接站，使得可以同时进行电气和流体连接。在安装过程中，无论零件公差如何，都会将一致的插入力（如弹簧加载的肘节机构）施加到打印头。
