摘要： An apparatus and method for delivery of sheet media to a printer includes a chassis, a drive motor, a media tray with elevatable pressure plate, a plurality of pick rollers situated opposite movable pinch rollers that come into contact with the pick rollers to form a roller assembly therebetween when in an extended position. A movable separator forms a throat between one of the pick rollers and the leading edge of the separator when it is in an extended position. A common transmission is used to simultaneously position the pinch rollers, separator, and the pressure plate. The apparatus also includes a media retarder for preventing multiple sheets of media from advancing through the apparatus at the same time. The method includes delaying the rotation of the pick rollers until a stack of media has been raised to press against the pick rollers, and the pinch rollers and separator are in an extended position. The pinch rollers and separator are retracted, and the transmission is disengaged from the pick rollers once the media sheet is delivered to a printer feed system.
摘要翻译：用于将片材介质输送到打印机的装置和方法包括底盘，驱动马达，具有可升高压力板的介质托盘，与可移动夹送辊相对的多个拾取辊，该拾取辊与拾取辊接触以形成辊当处于延伸位置时，它们之间的组件。当分离器处于伸出位置时，可动分离器在分离器之一和分离器的前缘之间形成喉部。常用的传动装置用于同时定位夹送辊，分离器和压板。该装置还包括用于防止多张介质同时前进通过设备的介质延迟器。该方法包括延迟拾取辊的旋转，直到一叠介质被升高以压靠拾取辊，并且夹送辊和分离器处于伸出位置。夹送辊和分离器缩回，并且一旦介质片被输送到打印机进给系统，变速器就从拾纸辊脱离。

摘要： A mechanism for manifolding a vacuum force to separate surface sectors of a vacuum holddown uses subsurface ducting to apply the vacuum to separate subsurface vacuum plenums wherein each is fluidically coupled to a separate surface sectors. The plenum is segregated by a diaphragm into surface side and vacuum side cavities. Trigger ports and appropriate ducting through the holddown subjacent the surface associated with each sector determine how the vacuum is routed. Only when a trigger port is covered is the vacuum routed to the surface sector associated therewith. The system can be implemented in planar or curvilinear constructs and be provided with features to accommodate a near-continuous range of flexible material sizes. A specific implementation in an ink-jet hard copy apparatus is also described.

摘要： A novel ink-jet printer (10) is provided. The print provides both paper supply tray (12) and paper collection tray (18) in the front (14) of the printer for ease of paper handling and reduced footprint. The paper collection tray is provided with a pair of opposed output rails (22) which support a sheet of paper (16c) during printing to permit ink on a sheet of paper (16b) previously printed to dry. A paper handling mechanism is provided which eliminates a sheet pickup motor and associated elements. The paper handling mechanism is configured to pick off a sheet of paper from a stack of input paper, bring it around paper drive rollers (24) onto a platen (26), where the printing operation, employing a printhead cartridge (32), occurs. The printer further includes a service station (230) for clearing clogged nozzles in the printhead (33) and removing bubbles therefrom, for covering the nozzles with a protective cap (266), and for wiping contaminants off the nozzles. Reference pads (200) are provided for aligning and securing the printing cartridge in a carriage (35). The carriage is associated with a carriage guide (27), to which the carriage and print medium are referenced. The resulting printer is easy to manufacture, has reduced complexity by eliminating components in the paper drive mechanism and is lower in cost.
摘要翻译：提供了一种新颖的喷墨打印机（10）。该打印机在打印机的前面（14）内提供供纸托盘（12）和纸张收集盘（18），以方便纸张处理和减少占地面积。纸张收集盘设置有一对相对的输出轨道（22），其在打印期间支撑一张纸（16c），以允许预先打印干燥的纸张（16b）上的油墨。提供了纸张处理机构，其消除了纸张拾取电动机和相关元件。纸张处理机构被配置为从一叠输入纸张拾取一张纸，将纸张驱动辊（24）周围带到压板（26）上，其中使用打印头墨盒（32）的打印操作发生。打印机还包括用于清除打印头（33）中堵塞的喷嘴并从其中除去气泡的维修站（230），用于用保护盖（266）覆盖喷嘴，并且用于从喷嘴擦拭污染物。提供参考焊盘（200）用于将打印盒对准和固定在托架（35）中。托架与托架引导件（27）相关联，托架和打印介质被引用到托架引导件（27）上。所得到的打印机易于制造，通过消除纸张驱动机构中的部件并降低了成本，降低了复杂性。

摘要： A belt-type support for moving print media such as paper through a printer includes a flexible belt that is supported in a manner such that friction is minimized and such that the paper that is supported on the belt is advanced precisely through the print zone of the printer. The support is provided in conjunction with a uniform distribution of vacuum pressure to the paper carried by the belt. In one preferred embodiment, there is provided a rigid, flat platen for supporting a uniformly porous belt. The platen has a number of rollers on its surface to minimize the friction developed between the platen surface and the moving belt. The platen surface also includes ports to provide a uniform distribution of vacuum pressure to the porous belt. In another embodiment, sliders are carried in the support surface of the platen to minimize frictional contact with the moving belt. Another embodiment includes substantially flat platen surface with a low-friction material layer disposed between the belt and platen surface for facilitating movement of the belt over the platen.

摘要： A vacuum holddown for sheet materials has a surface having a field of vacuum ports in which each individual port is gated. When a vacuum is applied to the underside of the holddown, the gates close. When a sheet of material is introduced onto a region of the field, the gates only within vacuum manifold passageway covered by the material are configured to spring open, applying a suction force to the sheet via the now opened ports. The holddown thus automatically adjusts to material size. An implementation for use in an ink-jet printer with cut-sheet print media is demonstrated.

摘要： In a printer, liquid ink is applied to a print medium as the medium is passed through the printer. A low pressure zone is generated along one surface of the print medium to hold a portion of the print medium substantially flat for a period of time during and after the liquid ink is applied to the print medium. By subjecting the portion of the print medium to the low pressure zone, cockling of the print medium is prevented.

摘要： A flexible frame onsert molded capping system has an elastomeric sealing lip onsert molded onto a flexible, flat, springy support frame, preferably with series of these sealing lips being molded on a single flexible frame to simultaneously seal several adjacent inkjet printheads. The frame has a border region with one or more cap bases attached to the frame by plural suspension spring elements. The suspension spring elements have both cantilever and torsional characteristics which allow the bases to tilt and twist independent of one another to seal each printhead, even when the orifice plates of adjacent printheads are not in a coplanar alignment. Use of a single piece frame, and onsert molding of the cap lips thereon, decreases the number of parts required to assemble an inkjet printing mechanism, leading to a more economical unit which is easier to assemble.

摘要： A high deflection capping system has an elastomeric sealing member with a sealing lip that, when viewed in cross section, forms a smiling-shaped seal against an inkjet printhead to provide improved printhead sealing, particularly when sealing over surface irregularities on the printhead. This high deflection sealing member may be onsert molded onto a support frame. A series of these sealing lips being molded on a single flexible frame to simultaneously seal several adjacent inkjet printheads, with the flexible frame having a border region with one or more cap bases attached to the frame by plural suspension spring elements. The suspension spring elements have both cantilever and torsional characteristics which allow the bases to tilt and twist independent of one another to seal each printhead. Alternatively, the support frame may be designed to support only a single high deflection sealing member. A venting system is also provided with vapor diffusion handling capabilities.
