Abstract:
1. A method of ejecting liquid from a liquid dispenser comprising: providing a liquid dispenser including a liquid supply channel, a liquid dispensing channel, and a liquid return channel, the liquid dispensing channel including a wall, the wall including a surface, a portion of the wall defining an outlet opening, the outlet opening including a downstream edge relative to a direction of liquid flow through the liquid dispensing channel, the downstream edge being sloped relative to the surface of the wall of the liquid dispensing channel, and a liquid return channel; providing a liquid that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel; and causing a liquid drop to be ejected from the outlet opening of the liquid dispensing channel by selectively actuating a diverter member to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel, wherein providing the liquid that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel includes providing the liquid under pressure sufficient to cause the liquid to serve as the primary motive force for liquid drop ejection.
