Abstract
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.
Claims20
A fluid ejection device comprising:
- nozzles;
- firing resistors corresponding to the nozzles, wherein each firing resistor and corresponding nozzle are located in zones on the fluid ejection device, and wherein each zone has at least one firing resistor and corresponding nozzle;
- and
- addressable select logic responsive to a select address to couple multiple fire pulses to the firing resistors in the zones so that selected firing resistors in the same zone are coupled to a same fire pulse.
A fluid ejection assembly, comprising:
- at least one fluid ejection device, each fluid ejection device including:
- nozzles;
- firing resistors corresponding to the nozzles, wherein each firing resistor and corresponding nozzle are located in zones on the fluid ejection device, wherein each zone has at least one firing resistor and corresponding nozzle;
- and
- addressable select logic responsive to a select address to couple multiple fire pulses to the firing resistors in the zones so that selected firing resistors in the same zone are coupled to a same fire pulse.
A method of firing a fluid ejection device, the method comprising:
- providing a select address;
- and
- coupling, based on the select address, multiple fire pulses to firing resistors located in zones so that selected firing resistors in the same zone are coupled to a same fire pulse, wherein each firing resistor and a corresponding nozzle are located in the zones, and wherein each zone has at least one firing resistor and corresponding nozzle.
