    摘要： An automatic document feeder with a drive system that can efficiently handle double-side scanning and accommodate more than one timing sequence for sequentially picking individual sheets from a stack using only two motors—a pick motor and a media motor. The automatic document feeder includes a pickup unit with a pick roller, a set of de-skew rollers, a main media path configured to guide a media sheet from the pickup unit to a scanning region and from the scanning region to an output tray, and a switch-back path configured to guide the media sheet back into the main media path. The drive system is operable to provide a high-speed picking mode and a delayed picking mode. In the high-speed picking mode, the pickup unit is driven by the pick motor to pull a subsequent media sheet from a stack of media sheet as soon as a previously pulled media sheet has passed the pick roller. In the delayed picking mode, the de-skew rollers are driven by the pick motor to advance the media sheet toward the scanning region and the subsequent media sheet is pulled from the stack by the pickup unit when the previously pulled media sheet has passed the de-skewed rollers.

    摘要： A pivotable duplexing unit is attached to the wall of a printer using a hinge having an axis that is substantially perpendicular to the base. A latch and catch holds the pivotable duplexing unit in a closed position relative to the wall of the printing apparatus. The wall includes a support member for the hinge, and the pivotable duplexing unit further includes a pin for pivoting in a support member of the hinge. The support member includes a bearing surface that is substantially parallel to the base. The pin member includes an end that makes pivotable contact with the bearing surface.

    摘要： An indexing service station services interchangeable first and second inkjet cartridges when installed with a third inkjet cartridge in a dual-cartridge carriage of an inkjet printing mechanism. For printing graphics and text, the first cartridge usually prints black ink, while the third cartridge prints full-colorant concentrations of colored ink. For printing photographic type images, the black cartridge for printing text is replaced with the second cartridge which is an imaging cartridge. The imaging cartridge carries ink formulations having reduced colorant concentrations, which, when used in conjunction with the full color cartridge, provide near photographic image quality, as well as crisp black text and line art. The service station has three separate sets of servicing tools for independent servicing of the black, full color, and imaging cartridges. The full color servicing tools are mounted on a singular tumbler assembly, whereas both the black and imaging cartridge servicing tools; are mounted on a combination tumbler assembly, with both tumbler assemblies being driven by an indexing gear assembly. Leaf springs bias printhead wipers away from the tumbler assemblies, with translational and torsional spring flexure accommodating for any lack of parallelism between the printheads and their associated wipers. A method is also provided of servicing the black, full color, and imaging cartridges when installed in the printing mechanism.

    摘要翻译： 当在喷墨打印机构的双盒托架中安装有第三喷墨墨盒时，索引服务站可互换的第一和第二喷墨墨盒。 对于打印图形和文字，第一个墨盒通常会打印黑色墨水，而第三个墨盒会打印全色着色剂浓度的彩色墨水。 为了打印照相类型的图像，用于打印文本的黑色墨盒被替换为作为成像墨盒的第二墨盒。 成像墨盒携带具有降低的着色剂浓度的墨水配方，当与全色墨盒结合使用时，其提供近摄像图像质量以及清晰的黑色文本和线条艺术。 维修站有三套独立的维修工具，用于独立维修黑色，全彩色和成像墨盒。 全彩色维修工具安装在单个滚筒组件上，而黑色和成像墨盒维修工具; 安装在组合制动栓组件上，两个制动栓组件由分度齿轮组件驱动。 板簧将打印头擦拭器偏离滚筒组件，平移和扭转弹簧弯曲可适应于打印头及其相关的擦拭器之间任何缺乏​​平行度。 还提供了一种在安装在打印机构中时对黑色，全彩色和成像盒进行维修的方法。
