Abstract

See full text

In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes an array of fluid actuators grouped into primitives. Each actuator is disposed in a fluid chamber. The fluidic die also includes an array of fluid sensors. Each fluid sensor is disposed within a fluid chamber and determines a characteristic within the fluid chamber. A data parser of the fluidic die extracts from an incoming signal, firing instructions and measurement instructions for the fluidic die. The measurement instructions indicate at least one of a peak measurement during a nucleation event and a reference measurement during a non-nucleation event. A firing controller generates firing signals based on the firing instructions and a measurement controller activates, during a measurement interval of a printing cycle for the primitive, a measurement for a selected actuator based on the measurement instructions.
