Abstract: An inkjet printhead includes an inkjet nozzle with a main actuator and at least one peripheral actuator in the same 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 to renew the inkjet nozzle to mitigate decap conditions. When the inkjet nozzle has not sat idle, only the main actuator is activated to jet ink drops.

Abstract translation: 喷墨打印头包括具有主致动器的喷墨喷嘴和在同一燃烧室中的至少一个外围致动器。 确定喷墨喷嘴是否已经怠速，例如在阈值时间段内不燃烧。 当喷墨嘴已经空闲时，主致动器和外围致动器都被激活以喷射至少一个墨滴以更新喷墨喷嘴以减轻掉色条件。 当喷墨嘴没有怠速时，只有主执行器被激活以喷射墨滴。
