摘要： An actuator can selectively switch a volume of a pressure chamber between a first state V1 and a second state V2, which is greater than V1. The actuator changes from the first state into the second state and then changes back into the first state to eject ink from an ejection port. A controller controls the actuator such that To/Tc falls within a range from 0.51 to 0.54. To represents the time period between time the actuator starts to change from the first state into the second state, to a time the actuator starts to change from the second state into the first state. Tc represents the period of proper oscillation of ink filling up the individual ink passage. The actuator is controlled so that a variation in ink ejection speed is prevented from being too large relative to the variation in the degree of deformation of the actuator.

摘要： An ink-jet recording apparatus includes an ink-jet head having actuators and an actuator controller. The actuator controller supplies to the actuator an ejection pulse signal that appropriately switches the actuator between two states. When a time period Si (i=1, 2, . . . n), which is from a printing start point T0 to a point Ti (i=1, 2, . . . n) at which the ejection pulse signal is firstly supplied to actuators each corresponding to each of n nozzles (n denotes an arbitrary natural number) that are intended to eject ink based on print data, is longer than a predetermined time period Tw1, the actuator controller supplies the vibration pulse signal to each of the actuators within the time period Si.
