ABSTRACT:
An ink-jet head is disclosed. The ink-jet head can include: a channel for holding ink, a nozzle connected with the channel, a pressurizing unit configured to apply pressure to the ink so as to eject the ink, a partition coupled to one side of the channel so as to block the channel, and an actuator configured to deform one side of the channel so as to open the channel. While pressure is applied to the ink, this pressure can be turned on and off, to provide pressure pulses for ejecting the ink. As such, with this arrangement, the ejection properties of the ink-jet head can be adjusted to various settings.
