摘要： A fluid ejection device has a nozzle group with a plurality of nozzle circuits and a fire controller in electronic communication with the plurality of nozzle circuits. The fire controller includes a fire data input for receiving fire data, a warm data input for receiving warm data, and a firing signal input for receiving a firing signal having a firing pulse preceded by a warming pulse. The fire controller is operable to conditionally modify the firing signal according to a state of warm data received via the warm data input and a state of fire data received via the fire data input. The fire controller is operable to forward the conditionally modified firing signal to one of the plurality of nozzle circuits to pass a current representative of the conditionally modified firing signal through a firing element of the particular nozzle circuit. Conditionally modifying the firing signal comprises either not modifying the firing signal, blocking the firing pulse and not blocking the warming pulse or blocking the firing pulse and the warming pulse.
