摘要：An apparatus (110) and method of operating a liquid drop emitter, such as an ink jet device (100), for emitting liquid drops of different volumes. The liquid drop emitter compris a chamber (11, 42), filled with a liquid, having a nozzle (30) for emitting drops of the liquid, a thermo-mechanical actuator (15) having a moveable portion within the chamber for applying pressure to the liquid at the nozzle, and apparatus (42; 44; 200) adapted to apply heat puls to the thermo-mechanical actuator. The method for operating compris applying a first heat pul having a first power P1, first pul duration τp1, and first energy E1 = P1 × τp1, displacing the movable portion of the actuator so that a drop is emitted having a first drop volume Vd1 and traveling substantially at the target velocity v0; and applying a cond heat pul having a cond power P2, cond pul duration τp2, and cond energy E2 = P2 × τp2, displacing the movable portion of the actuator so that a drop is emitted having a cond drop volume
Vd2 and traveling substantially at the target velocity v0, wherein Vd2 > Vd1, E2 > E1, τp2 > τp1 and
P2 < P1. An alternate method for operating caus the emission of drops having different volumes traveling at different velocities wherein all velocities are within a pre-determined drop velocity range, vd min to vd max· Further methods for operating an ink jet printhead cau the emission of drops having different volumes and velocities wherein the triggering of the drop emission is delayed so as to result in synchronized arrival times at a print plane.
