The present embodiment further comprises a first bore (317) disposed within an orifice layer (305) disposed proximate the first drop ejector and associated with the first drop ejector. The present embodiment also comprises a second drop ejector (304 and 408) associated with the firing chamber. The second drop ejector is configured to cause fluid having a second drop weight to be ejected from the firing chamber, wherein the second drop ejector includes a second heating element and second drive circuitry electrically coupled with the second heating element. The present embodiment further comprises a second bore (319) disposed within the orifice layer disposed proximate the second drop ejector, and the second bore is associated with the second drop ejector.

摘要： The present invention provides a method for optimising greyscale printing by designing the waveform pulses that are used to eject ink drops from a printhead as well as a printhead controller and a printer designed by the method. The pulse voltage, pulse width and pulse delay of each individual pulse of the waveform ejecting a single droplet from the printhead, are determined so as to achieve that ink drops created by merging different droplets have the same velocity and hit a printing substrate at about the same time.

摘要： The invention is vary the amount of the liquid discharged from a same discharge port, thereby realizing recording of multi gradation levels.
After the discharge of a first liquid droplet (66a), a second liquid droplet (66b) is discharged while the movable member (31) is still in a displaced state. In comparison with the first liquid droplet (66a), the second liquid droplet (66b) has a larger discharge energy and a larger speed, because the moving energy of the movable member (31) and the energy consumed for the liquid flow opposite to the discharge port (18) are smaller. Thus the first and second droplets are united to form a united droplet (66d) before landing on the recording medium (150). In this manner the amount of the discharged liquid can be varied.
摘要翻译：本发明改变从同一排出口排出的液体的量，从而实现多级灰度级的记录。在第一液滴（66a）排出后，第二液滴（66b）在可移动部件（31）仍处于移位状态的同时排出。与第一液滴（66a）相比，第二液滴（66b）具有更大的放电能量和更大的速度，这是因为可移动部件（31）的移动能量和与液体流动相反的液体消耗的能量排放口（18）较小。因此，第一和第二液滴在落在记录介质（150）上之前结合成一个联合液滴（66d）。以这种方式，排出液体的量可以变化。
