DUAL-MODE INKJET NOZZLE OPERATION

摘要

An inkjet printhead includes an inkjet nozzle (100; 700; 800) with a main actuator and at least one peripheral actuator in the same firing chamber (102). 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. The ink drops jetted by activating both the main and the peripheral actuators and the ink drops generated by activating only the main actuator have the same drop weight and drop velocity.
