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： A liquid ejection head includes a passage unit and an actuator. A nozzle for ejecting liquid and a common liquid chamber are formed in the passage unit. An individual liquid passage formed in the passage unit includes a first passage a pressure chamber, a second passage, and a restricted passage. The first passage communicates between the nozzle and the pressure chamber. The second passage communicates between the pressure chamber and the restricted passage. The restricted passage is smaller than the second passage in the sectional area perpendicular to the flow of the liquid. The actuator can selectively take a first state in which the volume of the pressure chamber is V1 and a second state in which the volume of the pressure chamber is V2 larger than V1. The actuator changes from the first state into the second state and then returns to the first state to eject the liquid from the nozzle. The individual liquid passage is designed so that Tc1 and Tc2 defined by predetermined expressions showing characteristics of the individual liquid passage satisfy a condition that Tc1/Tc2 is substantially not less than 4.7 and not more than 5.5.

摘要： A test sheet is set in a droplet discharge device at a first distance. At least one droplet is discharged toward the test sheet from a nozzle formed in the droplet discharge device to form at least one first dot on the test sheet. The test sheet is set in the droplet discharge device at a second distance differing from the first distance.

摘要： A printer is provided with an ink jet head and a controller. The ink jet head prints on a print medium by discharging ink. The ink jet head comprises a plurality of units. Each unit comprises a nozzle for discharging ink, a pressure chamber communicating with the nozzle, and a piezoelectric element facing the pressure chamber. The piezoelectric elements form at least two element lines. Each element line is formed by at least two piezoelectric elements aligned in a first direction. Each element line is aligned in a sec direction which is different from the first direction. The controller controls the ink jet head to print on the print medium by changing voltage applied to each piezoelectric element of the ink jet head. The controller controls timings at which the controller changes voltage applied to each piezoelectric element by the element line. It is preferred that a timing at which the controller changes voltage applied to one of the two adjacent element lines is different from a timing at which the controller changes voltage applied to the other of the two adjacent element lines.
