摘要： An inkjet printhead assembly includes at least one inkjet printhead having nozzles and firing resisters. The inkjet printhead assembly includes fire pulse generator circuitry responsive to a start fire signal to generate fire signals, each having a series of fire pulses. The fire pulse generator circuitry generates the fire signals by controlling the initiation and duration of the fire pulses. The fire pulses control timing and activation of electrical current through the firing resisters to thereby control ejection of ink drops from the nozzles. One embodiment of the inkjet printhead assembly includes multiple printheads disposed on a carrier to form a wide-array inkjet printhead assembly.

摘要： Printhead and printer arrangements that provide digital delay between firing signals for a common firing interval. The delay achieves a controlled, staggered generation of firing signals that reduces EMI and instantaneous power supply draw and reduces or eliminates certain shielding requirements. Various arrangements are provided, including the use of edge triggered digital delay elements, staggered firing signal generation from firing signal control logic and the use of analog delay elements.

摘要： A printhead assembly includes at least one printhead having an internal power supply path, a power regulator providing an offset voltage from the internal power supply path voltage, and multiple primitives. Each primitive includes a group of nozzles, a corresponding group of firing resisters, and a corresponding group of switches. The switches are controllable to couple a selected firing resister between the internal power supply path and the offset voltage to thereby permit electrical current to pass through the selected firing resister to cause a corresponding selected nozzle to fire.

摘要： An inkjet printing system having multiple independent power supplies for providing firing energy to the ink ejection elements of one or more printheads. Different ones of the power supplies can be connected to different print cartridges each of which prints a different color ink; to different arrays of ink ejection elements within a single print cartridge, where each array prints a different color ink; or to different sections of the ink ejection element array of a single printhead for a single color ink. The output of each power supply is independently set to an appropriate voltage level for each different print cartridge, ink ejection element array, or section of an array.

摘要： A wide-array inkjet printhead assembly includes a carrier and N printheads and a module manager disposed on the carrier. The module manager receives a serial input data stream and corresponding input clock signal from a printer controller located external from the inkjet printhead assembly. The module manager demultiplexes the serial data stream into N serial output data streams. The module manager provides the N serial output data streams and N corresponding output clock signals based on the input clock signal to the N printheads.

摘要： An fluid ejection device includes nozzles and includes firing resistors which correspond to the nozzles. Each firing resistor and corresponding nozzle are located in zones on the fluid ejection device where each zone has at least one firing resistor and corresponding nozzle. Addressable select logic responsive to a select address couples fire pulses to the firing resistors in the zones so that each firing resistor in each zone is coupled to the same fire pulse.
