摘要： Predetermined geometric constructs reduce heat loss in a vacuum platen and assist in the reduction of paper cockle in ink-jet printing. A vacuum platen for supporting media during printing is provided with a plurality of heating elements and surfaces interspersed with vacuum ports. The heater elements are laid into surface channels of the platen such that an insulative gap separates the heaters from the main platen support structure. In an alternative embodiment, an insulative gasket is provided for the gap.

摘要： A platen surface structure construct, particularly useful in a hard copy apparatus for a vacuum holddown, is configured by dimensioning print media platen surface structure channels and ports in order to ensure print media leading edge and trailing edge holddown. Moreover, the vacuum is distributed across the platen surface in accordance with predetermined dye flow characteristics based upon known dye composition and known print medium composition and such that print artifacts are not created by vacuum pulling wet dye through the capillaries of the medium.

摘要： Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop support. An upstream pinch roller holds the media sheet to the belt upstream of the print zone. A downstream pinch roller holds the media sheet to the belt downstream of the print zone. A guide shim extends along the media path from a position upstream of the upstream pinch roller, passed the upstream pinch roller under a printhead adjacent to the print zone. The location of a lead edge of the guide shim relative to the print zone determines the minimum bottom margin for the inkjet printing device. The guide shim presses the media sheet to the belt support and keeps the media sheet flat under the inkjet printhead as the printhead moves over the media sheet.

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 wet-dye hard copy apparatus is provided with a vacuum transport for moving print media from and input, through a print zone, to an output. In order to reduce high frequency paper cockle, the print media is subjected to a post-printing predetermined bending while the print dye thereon is drying. In an alternative embodiment, a post-ejection bending heating step is added prior to ejecting a printed print medium to the apparatus output.

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： Heat is uniformly conducted to print media in an ink-jet printer in conjunction with the uniform application of vacuum pressure to the media for supporting the media as it is conveyed on a heated belt through the printer. The heat is applied to the media by conduction, in a manner that does not overheat the print head of the printer nor interfere with the trajectory of the droplets expelled from the print head. The heat is applied to the media in the print zone as well as regions on either side of the print zone where the media enters and exits the print zone. The amount of heat applied to each of these regions is independently controlled, and can be related to the physical characteristics of the particular type of print media or inks that are used.

摘要翻译： 热量均匀地传送到喷墨打印机中打印介质，同时将均匀的真空压力施加到介质上，以便在介质通过打印机在加热的带上传送时支撑介质。 通过传导将热量施加到介质上，其方式不会使打印机的打印头过热，也不干扰从打印头排出的液滴的轨迹。 热量被施加到打印区域中的介质以及介质进入和退出打印区域的打印区域的任一侧上的区域。 施加到这些区域中的每一个区域的热量被独立地控制，并且可以与使用的特定类型的打印介质或油墨的物理特性有关。
