| 20100207981 | LIQUID EJECTING APPARATUS AND LIQUID EJECTING METHOD - A liquid ejecting apparatus includes a liquid ejecting head that ejects liquid from a nozzle. A head movement section moves the liquid ejecting head in a movement direction. A controller controls a movement ejection operation that ejects the liquid from the nozzle while moving the liquid ejecting head in the movement direction. If there is satisfied a decision condition that indicates that the ejection rate is excessive, the controller causes the number movement ejection operations related to a certain range to be larger than if the decision condition were not satisfied. With respect to second liquid being higher in viscosity than first liquid, the controller determines the number movement ejection operations related to the above-mentioned certain range by the above-mentioned decision condition determined as excess of the above-mentioned ejection rate at an ejection rate being smaller than that of the first liquid. | 08-19-2010 |
| 20110273500 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a liquid ejecting head with a plurality of nozzle groups each having a plurality of nozzles. Each nozzle ejects a liquid onto a landing target by an ejection pulse applied to the liquid. A movement unit relatively moves the liquid ejecting head and the landing target. A control unit sets an ejection timing of the liquid from the nozzles for each nozzle group according to a distance between the nozzles and the landing target. A driving signal generation unit generates driving signals including the ejection pulses, where a timing of each ejection pulse is based on the distance and a speed of the liquid as the liquid crosses the distance. The control unit selects the driving signal for each nozzle group based on the distance and applies a corresponding ejection pulse to the liquid. A liquid ejecting method is also provided. | 11-10-2011 |
| 20110316948 | BUBBLE TOLERANT MANIFOLD DESIGN FOR A LIQUID EJECTING HEAD - A liquid ejecting head includes pressure generating chambers; nozzles that communicate with respective pressure generating chambers; a manifold that communicates with a liquid introduction opening and that serves as a common flow channel for the multiple pressure generating chambers; liquid supply channels, having liquid supply openings that open into the manifold, that communicate between the manifold and the pressure generating chambers; and a pressure generating element that causes liquid to be ejected through the nozzles by generating pressure within the pressure generating chambers. At least one of the liquid supply openings is physically separated from at least one adjacent liquid supply opening, such as by a partition, which prevents air bubbles from moving between adjacent liquid supply openings. | 12-29-2011 |
