Abstract
An inkjet printhead includes an inkjet nozzle with a main actuator and a peripheral actuator in a firing chamber. A determination is made as to whether the inkjet nozzle has sat idle, e.g., not firing for a threshold period of time. When the inkjet nozzle has sat idle, both the main actuator and the peripheral actuator are activated to jet at least one ink drop. When the inkjet nozzle has not sat idle, only the main actuator is activated to jet ink drops.
