A liquid ejecting apparatus including a liquid ejecting head that ejects liquid; a head flow path connected to the liquid ejecting head, that supplies the liquid; an attaching member that is attachable at a position adjacent to the head flow path; and an opening/closing mechanism that opens the head flow path when the attaching member is attached at the adjacent position and closes the head flow path when the attaching member is removed from the adjacent position.

Liquid ejecting apparatus

A liquid storage container includes a liquid storage section configured to store a liquid, a liquid injection section connected to the liquid storage section and configured to inject the liquid into the liquid storage section, an air chamber communicated with air, an air introduction section communicated to the air chamber and configured to introduce the air to the air chamber, a communicating passage through which the liquid storage section and the air chamber are communicated to each other, a liquid injection port defined as an intersection at which the liquid injection section and the liquid storage section intersect each other, and a connecting port defined between the liquid storage section and the communicating passage and located above the liquid injection port in a posture where the liquid injection port is oriented upward in a direction intersecting with a horizontal direction.

Liquid storage container and liquid jet apparatus

A liquid storage container includes a liquid storage section configured to store a liquid, a liquid injection section configured to inject the liquid into the liquid storage section, a liquid injection port defined as an intersection at which the liquid injection section and the liquid storage section intersect each other, an air chamber communicated with air, an air introduction path communicated to the air chamber and configured to introduce the air to the air chamber, a communicating passage through which the liquid storage section and the air chamber are communicated to each other, a first connecting port, which is a connecting port between the air introduction path and the air chamber, being located below a position that is lowered by a first distance from an upper end of the air chamber and located above a position that is raised by a second distance from a lower end of the air chamber in a posture where a liquid injection port is oriented upward in the intersecting direction, and a second connecting port, which is a connecting port between the communicating passage and the air chamber, in the intersecting direction in the posture, where the first distance is defined as a length of the first connecting port in an intersecting direction intersecting with a horizontal direction in the posture and the second distance is defined as a length of the second connecting port in the intersecting direction in the posture.

Liquid supply apparatus for supplying liquid to a liquid jet head and liquid container

A liquid ejection apparatus includes a liquid ejection unit including a nozzle formation surface in which an opening of a nozzle for ejecting liquid is formed; a wiper disposed so that the wiper can come in contact with the nozzle formation surface; and a liquid collection portion, which is capable of collecting liquid adhered to the wiper, disposed on an end side of the nozzle formation surface of the liquid ejection unit so as to be spaced apart from the nozzle formation surface in a wiping direction. The liquid collection portion includes a scraper having a scraping surface that scrapes off the liquid adhered to the wiper by coming in contact with the wiper, and a liquid absorbing material disposed at a position that does not come in contact with the wiper and at a position that comes in contact with an end portion of the scraping surface.

Liquid ejection apparatus

A liquid ejecting apparatus includes a liquid ejecting unit which includes a nozzle forming surface having nozzle openings for ejecting liquid formed thereon, a wiper which is contactably disposed on the nozzle forming surface, a movement unit which is able to relatively move the liquid ejecting unit and the wiper, and a control unit which controls the movement units such that an interference amount of the wiper and the nozzle forming surface in a position of the wiper which comes in contact with the liquid ejecting unit, is smaller than an interference amount of the wiper and the nozzle forming surface when the wiper is relatively moved through a nozzle region which is a region including the nozzle openings of the nozzle forming surface in a direction along the nozzle forming surface.

Liquid ejecting apparatus and wiping method

A liquid storage container includes a liquid storage section configured to store a liquid, a liquid injection section connected to the liquid storage section and configured to inject the liquid into the liquid storage section, a liquid injection port defined as an intersection at which the liquid injection section and the liquid storage section intersect each other, an air chamber communicated with air, an air introduction section communicated to the air chamber and configured to introduce the air to the air chamber, a communicating passage through which the liquid storage section and the air chamber are communicated to each other, and a collection section configured to collect the liquid and provided in a route of the communicating passage, the route being configured to send the air from the air chamber toward the liquid storage section and being a portion through which the air goes downward from above of the route in a posture where the liquid injection port is oriented upward in a direction intersecting with a horizontal direction.

A liquid ejecting apparatus which includes an ejection head capable of ejecting a liquid to an ejection object, a liquid source including a liquid container capable of containing the liquid, a flow channel capable of allowing the liquid to flow form the liquid source to the ejection head, and a pressure buffer disposed in the flow channel capable of buffering a variation in pressure of the liquid in the flow channel when the liquid container is detached from the liquid source.

Liquid ejecting apparatus and liquid supply method

A printer includes a cleaning mechanism that reliably performs an operation of cleaning a liquid ejecting head with a small amount of driving energy. The cleaning mechanism includes a cap manufactured by coinjection molding of a core part and an elastic part. The cap includes a bottom surface, an outer wall, and a partition wall dividing a cap inner space surrounded by the outer wall into two. A ratio of the elastic part in the partition wall is higher than that in the outer wall. With this structure, the partition wall is more elastically deformable than the outer wall. When the cap comes into contact with a nozzle surface of a recording head and covers nozzle rows, the outer wall comes into contact with the nozzle surface with a larger stress compared with the partition wall, and seals chambers where the nozzle rows on the nozzle surface are exposed.

A liquid ejecting apparatus includes a carriage moving between a liquid ejecting area and a non-liquid ejecting area in a first direction, a liquid ejecting head, having a nozzle formation face from which a liquid droplet is ejected, the liquid ejecting head mounted on the carriage, a slider moving between a non-capping position and a capping position relative to the nozzle formation face in accordance with the movement of the carriage, a capping member provided on the slider, the capping member sealing the nozzle formation face when the slider is positioned on the capping position, a first spring urging the slider, and a guide member provided on the slider, and pushing against a side face of the liquid ejecting head.

In an ink jet recording apparatus, a recording head is mounted on a carriage which reciprocately moves in a widthwise direction of recording paper. A subtank is mounted on the carriage for supplying ink. A main tank stores ink which is replenished to the subtank. An ink amount detector detects an amount of ink stored in the subtank. A replenishment controller controls replenishment of ink stored in the main tank to the subtank, in accordance with the ink amount detected by the ink amount detector.
