Abstract
A fluidic die may include a substrate supporting a fluid actuator address line and first and second groups of fluid actuators connected to the fluid actuator address line. The first group of fluid actuators may include first and second types of fluid actuators having different operating characteristics. The second group of fluid actuators may include the first and the second types of fluid actuators. The fluid actuators of the first and second groups have addresses such that a fluid actuator of the first type in the first group and a fluid actuator of the second type in the second group are both enabled in response to a single enabling event on the fluid actuator address line.
Claims18
A fluidic die comprising:
- a substrate supporting a fluid actuator address line;
- a first set of fluid actuators connected to the fluid actuator address line, the first set of fluid actuators comprising:
- a first subset of fluid actuators of a first type of fluid actuators;
- and
- a second subset of fluid actuators of a second type of fluid actuators having different operating characteristics than the first type of fluid actuators;
- a second set of fluid actuators connected to the fluid actuator address line, the second set of fluid actuators comprising:
- a third subset of fluid actuators of the first type;
- and
- a fourth subset of fluid actuators of the second type,
- wherein a first fluid actuator of the first type in the first subset of fluid actuators and a first fluid actuator of the second type in the fourth subset of fluid actuators are enabled responsive to a common address of a single address enabling event on the fluid actuator address line.
A fluidic die comprising:
- a substrate supporting a fluid actuator address line;
- a first set of fluid actuators connected to the fluid actuator address line, the first set of fluid actuators comprising:
- a first subset of fluid ejectors;
- and
- a first subset of fluid pumps;
- a second set of fluid actuators connected to the fluid actuator address line, the second set of fluid actuators comprising:
- a second subset of fluid ejectors;
- and
- a second subset of fluid pumps,
- wherein fluid ejectors of the first subset of fluid ejectors and fluid pumps of the second subset of fluid pumps are enabled by a first set of addresses, and wherein fluid pumps of the first subset of fluid pumps and fluid ejectors of the second subset of fluid ejectors are enabled by a second set of addresses,
- wherein a first fluid ejector of the first subset of fluid ejectors and a first pump of the second subset of fluid pumps are enabled responsive to a common address on the fluid actuator address line.
A method comprising:
- transmitting address enabling signals that enable a single address on a fluid actuator address line of a fluidic die to each of a first set of fluid actuators and a second set of fluid actuators;
- enabling, based on the single address, a first fluid actuator of a first type of fluid actuators in the first set of fluid actuators;
- and
- enabling, based on the single address, a second fluid actuator of a second type of fluid actuators in the second set of fluid actuators, the second type of fluid actuators each having an operational characteristic different than that of the first type of fluid actuators;
- transmitting primitive enabling signals to the first set of fluid actuators and the second set of fluid actuators;
- actuating the first fluid actuator in response to the first fluid actuator receiving a combination of the address enabling signals and the primitive enabling signals;
- and
- actuating the second fluid actuator in response to the second fluid actuator receiving a combination of the address enabling signals and the primitive enabling signals.
