摘要： According to one or more embodiments, the inkjet head includes an actuator and a driver. The actuator causes a pressure chamber to expand or contract. The driver applies an ejection pulse to the actuator to eject ink from the pressure chamber. The ejection pulse includes an expansion pulse having a width of 0.75 to 1.25 times a pressure propagation time of the pressure chamber, a rest period after the expansion pulse, and a contraction pulse after the rest period.

摘要： In an ink jet printhead have an elongate ink chamber and a nozzle at one end, a continuous flow of ink is provided through a high impedance channel communicating with the chamber close to the nozzle. Ink is ejected through the nozzle by generating longitudinal acoustic waves in the fluid chamber. A high velocity ink flow into the chamber from the channel sweeps away from the nozzle debris or bubbles that might otherwise block the nozzle.
