Abstract: 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.

Abstract: Accurate advance of a media sheet is achieved by carrying the media sheet on a belt loop. 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 toward the print zone. The guide shim advances with the bottom edge of the media sheet into the print zone to stabilize the trailing edge so as to allow for a smaller minimum bottom margin.

Abstract: In one example, an encoding station of a printing system forms a pattern of non-printed features onto flowing print media. The non-printed features are detected, and timing signals generated from the detected features. The timing signals cause the media to be printed at a desired resolution in the direction of the flow.

Abstract: Anisotropic thermal conditioning of print media is provided for liquid colorant printing, such as in ink-jet hard copy apparatus, by establishing discrete temperature zones across a platen surface. Heat transfer mechanisms associated with individually selectable heater elements rapidly establish substantially uniform temperature profiles in each zone.

Abstract: An ink-jet print head having a dual function thermal controller is disclosed. In a thin-film print head apparatus, a buried resistive layer is located generally circumscribing the other active elements of the print head, viz., the drop generators and the firing logic. During printing operations, the buried resistive layer is used to sense print head temperature. When the print head temperature falls beneath a predetermined minimum limit, the buried resistive layer is activated to act as a heater for the entire print head. Alternatively, the heater can be cycled at predetermined intervals.
