A liquid ejection apparatus includes a liquid ejection section configured to print by discharging a liquid from a nozzle, a liquid container having an accommodation chamber that stores liquid and an injection port that communicates with the accommodation chamber and into which the liquid is configured to be injectable from the outside, a supply flow path communicating between the liquid ejection section and the liquid container, and an opening and closing mechanism. The opening and closing mechanism that is configured to switch such that an open state in which the supply flow path is opened and a closed state in which the supply flow path is closed when power is turned on and not to switch when power is turned off.

Liquid ejection apparatus

A liquid ejecting apparatus includes a transport unit that transports a medium along a transport path, a liquid ejecting head that performs recording on the transported medium by ejecting liquid from a nozzle formed at a nozzle surface, a mounting portion on which a liquid storage portion for storing the liquid supplied to the liquid ejecting head is mounted, and a first discharge port that delivers the medium on which the recording is performed toward a media processing apparatus that performs processing on the medium, in which the mounting portion is disposed at a position higher than the nozzle surface, and a first transport path which is a portion of the transport path from a position corresponding to the liquid ejecting head to the first discharge port passes above the mounting portion.

Liquid ejecting apparatus and recording system

A liquid ejection apparatus includes a liquid ejection head that is detachably attached and ejects a liquid, and a control section that is configured to transmit a delivery request for a new liquid ejection head to a server apparatus via a network.

Liquid ejection apparatus and delivery system for liquid ejection head

A liquid ejecting apparatus including a transporting portion that transports a medium along a transport path, a liquid ejecting head that performs recording by ejecting, through a nozzle, a liquid onto the medium that is being transported, a mounting portion in which a liquid storage portion that stores the liquid supplied to the liquid ejecting head is mounted, and a heating portion that heats the medium on which the recording has been performed. The transport path includes an upper path positioned above the mounting portion in a vertical direction. After transporting and passing the medium, on which the recording has been performed, through the upper path, the transporting portion discharges the medium through a discharge port. The heating portion is provided above the mounting portion in the vertical direction and heats the medium transported through the upper path.

A liquid ejecting apparatus includes: an ejection portion that ejects liquid onto a medium; a waste liquid container having a container that is configured to store a waste liquid discharged from the ejection portion; a housing that houses the ejection portion; and a humidity adjustment portion that adjusts humidity inside the housing. The waste liquid container is configured to store moisture discharged from the humidity adjustment portion.

Liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head that ejects liquid through a nozzle, a supply flow path that supplies liquid from a liquid container containing liquid to the liquid ejecting head, a liquid chamber provided in a buffer chamber disposed in the supply flow path, the liquid chamber being configured to change in volume, a liquid feeding unit of a reversible type disposed in the supply flow path between the liquid container and the liquid chamber, a control portion that controls driving of the liquid feeding unit, and a suction unit that suctions liquid through the nozzle. The control portion controls the liquid feeding unit to perform reverse feeding of the liquid from the liquid chamber to the liquid container before the suction unit suctions the liquid through the nozzle.

Liquid ejecting apparatuses

A method for manufacturing a refilled cartridge for performing refilling of printing material after use of a cartridge is provided. The cartridge includes a first case including a recess having a bottom surface and an opening, a flexible portion attached to the opening, a second case covering the open surface of the first case, a pressure receiving portion contacting the flexible portion, a chamber of variable capacity and a biasing member that generates negative pressure inside the chamber The printing material is refilled into the chamber so that two or more points across the biasing member on the pressure receiving portion do not contact the second case after refilling of the printing material is completed.

Refilled cartridge and method for manufacturing refilled cartridge

A liquid ejecting apparatus includes a liquid ejecting portion configured to eject a liquid, a liquid supply flow path of which a downstream end portion is attachably/detachably connected to the liquid ejecting portion and through which the liquid is supplied from a liquid accommodating portion that accommodates the liquid to the liquid ejecting portion, an opening/closing valve capable of opening and closing the liquid supply flow path, an atmosphere communication path connected to the liquid supply flow path on a downstream side of the opening/closing valve, an atmosphere release valve capable of opening and closing the atmosphere communication path, a suction mechanism capable of sucking the liquid in the liquid ejecting portion, and a control device configured to control operations of the opening/closing valve, the atmosphere release valve, and the suction mechanism.

Liquid ejecting apparatus and method of replacing liquid ejecting head

A liquid ejecting apparatus includes a liquid ejecting head which performs a printing by ejecting liquid onto a medium from a nozzle, a wiping portion which wipes the liquid ejecting head by moving relative to the liquid ejecting head, a maintenance unit which performs a maintenance to forcibly discharge the liquid from the nozzle, and a preprocessing device which performs a preprocessing on the medium before the printing is performed, in which when the wiping portion and the liquid ejecting head are separated from each other in the wiping not accompanying the maintenance, the wiping portion is displaced in a direction away from the preprocessing device.

A liquid ejecting apparatus includes a liquid ejecting head which ejects a liquid from a nozzle onto a medium, a liquid storage member which stores the liquid to be supplied to the liquid ejecting head, and a carriage on which the liquid ejecting head and the liquid storage member are installed and which is capable of moving on a movement path. The liquid storage member includes a liquid filling port which is disposed above the liquid ejecting head and is for filling the liquid. The liquid filling port is provided at a position which does not overlap with a nozzle forming surface in which the nozzle is formed in plan view from above.

A liquid ejecting apparatus includes a liquid ejecting portion that has a nozzle and an opening surface in which the nozzle opens and that ejects a liquid from the nozzle toward a medium that is transported along a transport path, a wiper member that wipes the liquid ejecting portion while moving, a guide that guides movement of the wiper member, and a cap that has an opening portion and that is movable between a capping position at which the cap contacts the liquid ejecting portion so that the opening portion surrounds the nozzle and an open position at which the cap is apart from the liquid ejecting portion. When the cap is at the open position vertically below the guide, the opening portion is at least partially covered by the guide.

A liquid ejecting apparatus includes: a liquid ejecting head that ejects liquid; a first tank that stores the liquid to be supplied to the liquid ejecting head; a second tank that receives the liquid that was not ejected from the liquid ejecting head; circulation paths through which the liquid circulates among the first tank, the liquid ejecting head, and the second tank; a pump that feeds the liquid from the second tank to the first tank; a first supply flow path that communicates between the first tank and a first main tank that is located above the first tank and stores the liquid; a second supply flow path that communicates between the first main tank and the second tank; a first opening/closing valve that can open and close the first supply flow path; and a second opening/closing valve that can open and close the second supply flow path.
