Abstract: In an example, a piezoelectric printhead assembly includes a micro-electro mechanical system (MEMS) die including a plurality of nozzles. An application-specific integrated circuit (ASIC) die is coupled to the MEMS die by a plurality of wire bonds, wherein each of the wire bonds corresponds to a respective nozzle of the plurality of nozzles. An arbitrary data generator (ADG) on the ASIC is to provide a digital data sequence, and a multiplier is to scale multiple nozzles of the plurality of nozzles.

Abstract: A wide array printhead module includes a plurality of printhead die, each of the printhead die includes a number of nozzles. The nozzles form a number of primitives. A nozzle firing heater is coupled to each of the nozzles. An application specific integrated circuit (ASIC) controls a number of activation pluses that activate the nozzle firing heaters for each of the nozzles associated with the primitives. The activation pulses are delayed between each of the primitives via internal delays and external delays to reduce peak power demands of the printhead die. The ASIC determines the internal delays within each printhead die.

Abstract: Systems and methods for evaluating the condition of a print nozzle are described. In one example, impedances across the print nozzle are measured. Subsequently, first test result and second test result are determined and registered at a first predetermined time instant and at a second predetermined time instant, respectively. The first test result and the second test result are obtained based on the measured impedances. Based on the first test result and the second test result, the condition of the print nozzle, is determined.

Abstract: In some examples, a fluid die includes a fluid nozzle, a first latch, a second latch, and a timing circuit comprising a counter and a comparator. The timing circuit is to trigger the first latch, at a first predetermined time instant from an edge of a firing pulse, to store a first test result obtained based on a voltage measured across the fluid nozzle, and trigger the second latch, at a second predetermined time instant from the edge of the firing pulse, to store a second test result obtained based on a voltage measured across the fluid nozzle.
