    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: 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: 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.
