摘要： To maintain a uniform spacing between the print media, such as paper, and an inkjet printhead having a large print swath, for instance about 25 millimeters (one inch) wide, a new media support system is provided for inkjet printing mechanisms, such as printers or plotters. The support system employs an endless belt driven from the belt interior surface by a roller drive system that uniformly supports the print media under the reciprocating printhead. The belt may be lined with anti-cockle ribs to support the media when saturated. The belt may also be foraminous, with a vacuum applied thereunder to pull the media onto the belt. A method is also provided for supporting and transporting a large sheet of print media through a printzone of an inkjet printing mechanism, such as an inkjet plotter, that uses such a large swath inkjet printhead.

摘要： A sheet media handling system is provided for use in a sheet processor (e.g., a printer). Such system incorporates an input tray for storing one or more sheet media prior to input through the printer's input port with the input tray vertically stacked with the printer's output support structure or tray. The system also has a single sheet medium guide mechanism adjacent the printer's output support structure, where the medium guide mechanism routes a single medium to the input port when the single medium is inserted therein. The single sheet medium guide mechanism includes a skew-abatement substructure and a deflection mechanism. The skew-abatement substructure is designed to facilitate alignment of and routing of a single medium towards the input port by contacting a first edge of the single medium and an opposite second edge of the single medium. Such a deflection mechanism is designed to deflect a single medium toward and into the input port by contacting the upper surface of the single medium while also contacting the lower surface of the single medium. The invented system facilitates easy manual insertion and alignment of a single medium (e.g., an envelope or postcard) into the input port of a printer without affecting the existing supply of sheet media in the input tray.
摘要翻译：提供了用于片材处理器（例如打印机）的片材介质处理系统。这样的系统包括用于在通过打印机的输入端口输入之前存储一个或多个纸张介质的输入托盘，其中输入托盘与打印机的输出支撑结构或托盘垂直堆叠。该系统还具有与打印机的输出支撑结构相邻的单张介质引导机构，其中当单介质插入其中时，介质引导机构将单个介质路由到输入端口。单张介质导向机构包括偏斜减小子结构和偏转机构。偏斜减小子结构被设计为通过接触单个介质的第一边缘和单个介质的相对的第二边缘来促进单个介质朝向输入端口的对准和布线。这种偏转机构被设计成通过接触单个介质的上表面而同时接触单个介质的下表面而使单个介质朝向和输入到输入端口。本发明的系统便于将单个介质（例如，信封或明信片）手动插入和对准到打印机的输入端口中，而不影响输入托盘中现有的片材介质的供应。

摘要： A sheet stacking system is provided which includes mechanism designed to compensate for the aerodynamic forces which act on a sheet as it passes from the printer's output port to the floor of the printer's output tray. The system includes a pair of spaced, anti-sail wings which are positioned adjacent the printer's output port so as to controlledly receive just-expelled sheets. The wings are operatively associated with the output tray's floor, and are arranged so that opposite movement thereof results in rear-to-front sequential release of a supported sheet, directing substantially vertical passage of such sheet to the top of an output stack.
摘要翻译：提供了一种纸张堆叠系统，其包括被设计成补偿当纸张从打印机的输出端口传送到打印机的出纸盘的地板时作用在纸张上的空气动力的机构。该系统包括一对间隔开的防风翼，其位于打印机的输出端口附近，以便受控地接收刚刚排出的纸张。翼部与输出托盘的地板可操作地相关联，并且被布置成使得其相反的运动导致受支撑片材的从前到后的顺序释放，将这种片材的基本垂直通道引导到输出叠层的顶部。

摘要： A separator is provided for use in a sheet pick-up system, the separator including a rigid body having a base portion and a wear-resistant upstanding portion. The separator is mounted adjacent the printer's input port and is biased toward a motor-driven roller, pinching input sheets between the roller and the separator's upstanding portion so that the roller may pull the top sheet across the second sheet and the upstanding portion. A frictionally adherent pad is formed in operative association with the body so as to extend in a region forward of the upstanding portion and contact the second sheet to oppose intake thereof.
