20120026220 | LIQUID EJECTION APPARATUS - A liquid ejection apparatus including: a liquid ejection head including: an inlet opening; an outlet opening; an inside channel; and ejection openings; a tank; a supply channel; a return channel; a supply device; and a controller, wherein the controller is configured to control the supply device to perform a circulating operation in which the liquid in the tank is transferred to the supply channel, the inside channel, and the return channel in order and returns to the tank, and wherein the controller is configured to control the supply device such that a unit-time supply amount that is an amount of the liquid to be supplied to the inside channel per unit time in a first period in the circulating operation is less than that in a second period that is after the first period. | 02-02-2012 |
20120026221 | LIQUID EJECTION APPARATUS - A liquid ejection apparatus including: a liquid ejection head including an inside channel; a supply channel; a return channel; a supply device; an adjusting device; and a controller, wherein the controller starts a liquid circulation control for circulating liquid through the supply channel, the inside channel, and the return channel in order by controlling: the adjusting device such that a channel resistance value of the return channel is less than a predetermined maximum value; and the supply device to supply the liquid into the inside channel, wherein, when the liquid is circulated, the controller starts a liquid discharge control for discharging the liquid by increasing the channel resistance value, wherein, when the liquid is discharged, the controller starts a liquid-discharge stopping control for stopping the discharge by decreasing the channel resistance value, and wherein the controller controls the supply device such that a liquid amount supplied to the inside channel per unit time when the discharge is stopped is less than that in the liquid circulation control. | 02-02-2012 |
20120026242 | LIQUID EJECTION APPARATUS - A liquid ejection apparatus including: a liquid ejection head including: an inside channel; and ejection openings; a supply channel; a return channel; a supply device; an adjusting device; and a controller, wherein the controller performs a liquid circulation control for circulating liquid through the supply channel, the inside channel, and the return channel in order by controlling (i) the adjusting device such that a channel resistance value of the return channel is less than a predetermined maximum value and (ii) the supply device to supply the liquid into the inside channel, wherein, when the liquid is circulated by the liquid circulation control, the controller starts a liquid discharge control for discharging the liquid by making the channel resistance value larger than that in the liquid circulation control, and wherein the controller controls the supply device such that an amount of the liquid supplied to the inside channel per unit time in the liquid discharge control is larger than that in the liquid circulation control. | 02-02-2012 |
20120162295 | LIQUID EJECTION APPARATUS AND STORAGE MEDIUM STORING PROGRAM - A liquid ejection apparatus including: a liquid-ejection head for ejecting image recording liquid; a sealing mechanism for sealing an ejection space; a humid-air supply mechanism storing humidification liquid; and a liquid-discharge portion for discharging the image recording liquid, wherein a controller controls the humid-air supply mechanism to supply an air humidified by the humidification liquid into the sealed ejection space and then controls the liquid-discharge portion to discharge the image recording liquid prior to the image recording, and wherein, where a remaining amount of the humidification liquid is less than a first value, the controller executes a control such that an amount of the supplied humid air and an amount of the discharged image recording liquid are respectively made small and large as compared with in a case where the remaining amount of the humidification liquid is not smaller than the first value. | 06-28-2012 |
20140376948 | CARTRIDGES AND RECORDING APPARATUSES - A cartridge includes a substrate and an engagement portion. The first surface faces a first direction and has a first surface on which an electrical terminal is disposed. The engagement portion includes a second surface disposed upstream from the substrate in the first direction and a third surface. The second surface faces a second direction, which forms an obtuse angle with the first direction. The third surface faces a third direction, which forms an acute angle with the first direction. The third surface does not overlap with the substrate in the first direction and the third surface is disposed downstream from the second surface in the first direction. | 12-25-2014 |
20150283815 | LIQUID CONSUMING APPARATUS - There is provided a liquid consuming apparatus which includes a tank including first and second liquid storage chambers, and a liquid consuming unit. The tank includes a first inlet, a first atmosphere communication channel, a first liquid outflow channel, a first return channel, a second inlet, a second atmosphere communication channel, a second liquid outflow channel, and a second return channel. A volume of the first liquid outflow channel from the first position up to the second position and a volume of the second liquid outflow channel from the fourth position up to the fifth position differ mutually. | 10-08-2015 |
20150283832 | LIQUID JETTING APPARATUS - A liquid jetting apparatus includes a casing, a tank formed with a liquid storage chamber which stores liquid, an inlet which allows the liquid to be poured into the liquid storage chamber, and a liquid outflow channel which allows the liquid to flow out from the liquid storage chamber, a conveying mechanism which conveys a recording medium along a conveying path extending in a front-rear direction, a carriage which moves in a left-right direction, and a head mounted on the carriage and having a nozzle which jets the liquid onto the recording medium conveyed by the conveying mechanism. The tank, the conveying path, and the carriage are arranged inside the casing, the tank is arranged outside the conveying path in the left-right direction, and at least a part of the tank is arranged inside both ends of a movement area of the carriage in the left-right direction. | 10-08-2015 |
20150284170 | LIQUID DISCHARGE APPARATUS - There is provided a liquid discharge apparatus which includes a tank including a liquid storage chamber, an inlet, a liquid lead-out channel, and an atmosphere communication channel, a conveyance mechanism, a carriage, and a head. A lower end of the inlet is positioned at a lower side of the nozzles, and the liquid storage chamber is arranged at a position shifted from the nozzles, in a first-direction side of the front-rear direction, and shifted from the conveyance route, to a second-direction side of the left-right direction. The liquid storage chamber is connected to the liquid outflow channel at a position on a lower side of a center in a up-down direction of the liquid storage chamber, and in the first direction from a center in the front-rear direction of the liquid storage chamber, and on the second-direction side of a center in the left-right direction of the liquid storage chamber. | 10-08-2015 |
