Abstract: 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.

Abstract: A method and apparatus for ink-jet drop generator ink drop characteristics uses a drop detector target mounted in the printing zone of a hard copy apparatus. The detector target includes a matrix of individual elements sized approximately the same as pixel targets in printing operations. A detector target is mounted adjacently to the paper path of the apparatus such that test firing can be accomplished prior to each swath scan across the print media. By pre-firing nozzles to be used in the next swath at the detector target, actual trajectory errors and drop volumes can be analyzed in real-time. Alternate embodiments and methods are described.

Abstract: An embodiment of a drying apparatus for drying ink deposited onto media includes an electromagnetic energy source to generate electromagnetic energy. The embodiment of the drying apparatus also includes a rectangular waveguide coupled to the electromagnetic energy source. The rectangular waveguide includes slots in the axial direction of the rectangular waveguide on opposite sidewalls corresponding to the largest sides forming a cross section of the rectangular waveguide. The electromagnetic energy source is configured to establish a TE01 mode within the rectangular waveguide, resulting in an electric field substantially perpendicular to the longitudinal axes of fibers within the media and thereby reducing power dissipated within the media while providing sufficient power for drying the ink during a drying operation.

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: 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.
