Abstract
A fluid ejection device may include fluid actuators and an actuation controller. Each fluid actuator may have an associated address. The actuation controller is to receive an address for a fluid actuator of the device to be actuated and is further to automatically transmit one of different fire pulses based upon the received address.
Claims13
A fluid ejection device comprising:
- a substrate;
- fluid actuators on the substrate, each fluid actuator having an associated address, wherein the fluid actuators comprise:
- ejection fluid actuators of ejectors to eject fluid through nozzles;
- and
- circulation fluid actuators to circulate fluid with respect to the ejectors;
- and
- an actuation controller on the substrate, the actuation controller to:
- receive an address for a fluid actuator of the device to be actuated;
- and
- automatically transmit one of different fire pulses based upon the to be received address, wherein a first fire pulse is to be automatically transmitted in response to the to be received address corresponding to an address of one of the ejection fluid actuators and wherein a second fire pulse is to be automatically transmitted in response to the to be received address corresponding to an address of one of the circulation fluid actuators.
7 more elements
A method comprising:
- receiving instructions, with an actuation controller on a substrate of a fluid ejection device, the fluid ejection device comprising ejection fluid actuators of ejectors to eject fluid through nozzles;
- and circulation fluid actuators to circulate fluid with respect to the ejectors, the instructions to actuate a fluid actuator on the substrate at a given address;
- and
- automatically transmitting, with the actuation controller on the fluid ejection device, one of a first fire pulse and a second fire pulse, different than the first fire pulse, based upon the given address, wherein the automatically transmitting comprises automatically transmitting the first fire pulse in response to the given address corresponding to an address of one of the ejection fluid actuators and automatically transmitting the second fire pulse in response to the given address corresponding to an address of one of the circulation fluid actuators.

A fluid ejection system comprising:
- a fluid ejection controller to transmit instructions to a fluid ejection device, the instructions comprising an address of a fluid actuator on the fluid ejection device to be actuated;
- and
- the fluid ejection device comprising:
- a substrate;
- fluid actuators on the substrate, each fluid actuator having an associated address, the fluid actuators comprising ejection fluid actuators of ejectors to eject fluid through nozzles and circulation fluid actuators to circulate fluid with respect to the ejectors;
- and
- an actuation controller on the substrate, the actuation controller to:
- receive the address for the fluid actuator of the device to be actuated;
- and
- automatically transmit one of different fire pulses based upon the received address, wherein a first fire pulse is to be automatically transmitted in response to the received address corresponding to an address of one of the ejection fluid actuators and wherein a second fire pulse is to be automatically transmitted in response to the received address corresponding to an address of one of the circulation fluid actuators.
