Abstract: The liquid jetting apparatus includes a head member having a nozzle, a supporting member that that can support a medium, a scanning mechanism that can cause the head member to relatively move with respect to the medium, and a liquid jetting unit that can jet liquid from the nozzle. An area storing unit stores a relative area to which liquid can be jetted from the nozzle while the head member is caused to relatively move by the scanning mechanism. An out-of-jetting micro-vibrating-area setting unit can set out-of-jetting micro-vibrating areas before and after the relative area. A micro-vibrating unit causes liquid, in the nozzle to minutely vibrate. An out-of-jetting micro-vibrating controlling unit causes the micro-vibrating unit to operate when the head member is located in the out-of-jetting micro-vibrating areas, while the head member is caused to relatively move by the scanning mechanism, based on the out-of-jetting micro-vibrating areas and head-position information.

Abstract: In the bi-directional printing, a reference correction value is set for correcting printing positional deviation arising between forward and reverse main scanning passes with respect to specific reference dots. An adjustment value is determined, using at least the reference correction value, to reduce printing positional deviation arising between forward and reverse main scanning passes. The printing positional deviation between forward and reverse main scanning passes is adjusted using the adjustment value. In a first adjustment mode, the adjustment value is determined by correcting the reference correction value with a relative correction value prepared beforehand for correcting the reference correction value.

Abstract: The liquid-jetting apparatus has a liquid-jetting head with nozzle openings through which liquid particles are jetted. The liquid-jetting head performs a flushing operation to remove the thickened liquid from the nozzle openings to recover its normal liquid-jetting ability. The flushing operation jets liquid particles having a weight of 10 ng or below successively through the nozzle openings at a jetting speed of 8 m/s or above. The liquid-jetting apparatus is capable of achieving a satisfactory flushing operation to ensure a satisfactory liquid-jetting characteristic by recovering from a thickened state in a liquid in the nozzle openings even if the liquid is un-uniformly thickened in the nozzle openings.

Abstract: During printing, print head characteristics are taken into consideration to alleviate positional deviation of dots in a main scanning direction and improve image quality. The print head unit is provided with readable head identification information that is set in accordance with characteristics relating to positional deviation of dots to be formed by the print head in a main scanning direction. In accordance with this head identification information, adjustment values are determined for reducing printing positional deviation in the main scanning direction, and these adjustment values are used to adjust the position of dots in the main scanning direction.

Abstract: The technique of the present invention improves the accuracy of calculating an amount of ink consumption in an ink reservoir used in a printer, which ejects ink stored in the ink reservoir and prints an image. In the printer of the present invention, a weight of a single ink droplet is measured in advance under a preset reference condition. In the course of printing an image, the printer detects an ink supply condition, which affects the weight of a single ink droplet, and counts a number of ink droplets ejected. The amount of ink consumption is determined by correcting a product of the measured weight of a single ink droplet and the counted number of ink droplets based on a difference between the detected ink supply condition and the preset reference condition. This arrangement calculates the amount of ink consumption by taking into account the ink supply condition, thereby improving the accuracy of calculation for the amount of ink consumption.
