摘要： A method for servicing a printhead includes moving the printhead along a first path away from a printing position adjacent a drum to a service position away from the drum, moving a service station carrying a printhead service element through an arc-shaped second path from a rest position to a servicing position, and conducting a service operation with the service element on the printhead at the service position.

摘要： Described are techniques for preventing the forces attributable to shrinkage of print media from shifting print media on the media-carrying belt in the vicinity of the print zone. In one approach, a “hold zone” is identified immediately upstream of the print zone. In the hold zone, a mechanism is employed for securing the media to be immovable relative to the belt. The hold mechanism provides sufficient force to overcome tension transmitted to the dry portion of the media as the remaining portion shrinks. In one embodiment, the hold mechanism is a roller that pinches the media against the belt. In another embodiment, the amount of vacuum pressure applied to the belt is regulated so that the suction force applied to the media in the hold zone is greater than the suction force applied to the media in the portion upstream of the hold zone.

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： An inkjet printer includes a microwave drying station passing media through a waveguide thereof. A vacuum source coupled to the waveguide draws air into the waveguide and thereby aides in disturbing and scrubbing a boundary layer of vapor at the media surface otherwise hindering efficient drying of media thereat. Supporting the media on a perforated belt through the waveguide couples media to the belt by vacuum force and thereby contributes to an overall media feed mechanism.

摘要： A print media preheating method and apparatus uses heat, vacuum, and mechanisms for drying and flattening a sheet prior to ink-jet printing thereon. Pre-shrinking the media, driving out and substantially reducing inherent moisture content prior to depositing wet ink thereon provides greater flatness in the print-zone whereby ink-jet print quality is improved.

摘要： Techniques for providing a face down orientation of printed media at a normally face up output of a printer. One technique achieves correct order orientation in a printer having a duplexing function, and includes printing a page of the print job at a print area, passing the page through a duplexing media path to reorient the page in a page down orientation, passing the page through the print area in the page down orientation without conducting a printing operation, and passing the page from the print area to an output area in correct order orientation. Another technique includes advancing a page from an input source to a print area, conducting printing operations on the page at the print area, transporting the page away from the print area, diverting the page into an auxiliary media path portion and transporting the page, leading edge first, until a trailing edge of the page passes a diverter location, transporting the page in the reverse direction such that the trailing edge now becomes the leading edge, and diverting the present leading edge of the page along a media path leading to the normally face up output, such that the page is presented to the normally face down output in a face down orientation.

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.
