Abstract: First electronics may determine a count of bubble jet resistors to be fired by a fire pulse group. A fire pulse generator may generate a fire pulse train for bubble jet resistors, the fire pulse train comprising a precursor pulse and a firing pulse separated by a dead time. Second electronics may adjust a width of the fire pulse for the bubble jet resistors of the fire pulse group by maintaining a first edge of the fire pulse relative to the precursor pulse and adjusting a second edge of the fire pulse relative to the precursor pulse based upon the determined count for the fire pulse group.

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: Examples include a fluid ejection die. Examples comprise a set of nozzles, where each respective nozzle includes a respective fluid ejector. Examples further include respective identification logic for each nozzle, where the respective identification logic is connected to the respective nozzle and fluid ejector thereof. Furthermore, the identification logic for each nozzle of the set has a component characteristic that is different from other identification logic for nozzles of the set. Accordingly, each identification logic is to output a different actuation signal responsive to actuation of the fluid ejector.

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: A fluidic die includes a number of actuators to eject fluid from the fluidic die. The number of actuators form a number of primitives. The fluidic die includes a plurality of delays within a column of the primitives, and a processing device to control the delays through which a number of activation pulses pass. The activation pulses activate each of the actuators associated with the primitives. The activation pulses are delayed between the primitives via at least one of the delays to reduce peak power demands of the fluidic die.

Abstract: An inkjet printhead including a plurality of printhead dies, each printhead die including at least one crack sense resistor, at least one analog bus connected to each printhead die, and a controller separate from the plurality of printhead dies. The controller is configured to provide a known current to the at least one crack sense resistor of each printhead die in a selectable pattern via the at least one analog bus and to determine whether the printhead dies are cracked based on resulting voltages produced on the at least one analog bus.
