Abstract: An apparatus and method support a plurality of print head dies (24, 324, 524) on a print bar (22, 322, 522). The plurality of print head dies (24, 324, 524) comprise a print head die (24, 324, 524) having a circuit (26, 526) forming a series (28, 328) of information bits (30), wherein bit locations in the series (28, 328) are mapped to information type definitions based on a location of the print head die (24, 324, 524) on the print bar (22, 322, 522) relative to other print head dies (24, 324, 524) on the print bar (22, 322, 522).

Abstract: A fluid-jet precision-dispensing device includes a layer, one or more first holes within the layer, and one or more second holes within the layer. The first holes are adapted to pass fluid therethrough during usage of the device to precisely dispense the fluid at accurately specified locations. The second holes are adapted to not pass the fluid therethrough during usage of the device to precisely dispense the fluid at the accurately specified locations. The second holes may be adapted to at least substantially maximally pass gaseous bubbles therethrough during performance of a priming operation of the device. The second holes may be adapted to at least substantially maximally pass sludge and/or contaminants therethrough during performance of the priming operation of the device.

Abstract: Various configurations of print head die are described. In an example, a first print head die has first print structures disposed along a major dimension thereof perpendicular to the media path, the first print structures including a leading print structure with respect to the media path. A second print head die independent of the first print head die has second print structures disposed along a major dimension thereof perpendicular to the media path, the second print head die being staggered with respect to the first print head die along the media path, the second print structures including a leading print structure with respect to the media path. A portion of the second print structures overlap a portion of the first print structures by an extent between a minimum value and a linear function of a separation between the respective leading print structures of the first and second print head dies.

Abstract: A print head die with thermal control is described. In an example, a print head die includes a substrate having liquid feed slots formed therein extending along a major dimension of the substrate and nozzles extending along opposite sides of each of the liquid feed slots; a temperature sensor formed on the substrate adjacent to a first one of the liquid feed slots; and electrical interconnect formed on the substrate along the major dimension adjacent to a last one of the liquid feed slots farthest from the first liquid feed slot.
