Printing apparatus and printhead

A liquid discharge apparatus includes a liquid container and an operating member. The liquid container is configured to introduce liquid from a liquid introducing portion to an inside. The operating member is configured to rotate around a rotation shaft in a first direction from a first position for covering the liquid introducing portion to move to a second position for exposing the liquid introducing portion, and rotate in a second direction opposite to the first direction from the second position to move to the first position. The operating member includes a plug member and a covering portion. The plug member is retained to the operating member by a retaining member and configured to plug the liquid introducing portion at the first position. The covering portion is configured to cover the plug member in a direction intersecting with the first direction.

Liquid discharge apparatus having liquid container and operating member

A liquid ejection apparatus includes a first liquid storage container, a second liquid storage container, a first terminal member, a second terminal member, and a circuit board. The first liquid storage container stores liquid to be supplied to a liquid ejection head that ejects the liquid to an ejection medium. The second liquid storage container is arranged side by side in a first direction with respect to the first liquid storage container. The first terminal member comes into contact with the liquid stored within the first liquid storage container. The second terminal member comes into contact with liquid stored within the second liquid storage container. The circuit board comes into contact with the first terminal member and the second terminal member and relatively moves in the first direction with respect to the first liquid storage container.

Liquid ejection apparatus

A liquid discharge apparatus includes a liquid discharge head to discharge liquid to a medium and a liquid storage container. The liquid storage container includes a reservoir portion, a liquid injection portion, a liquid holding unit, and a liquid guide portion. The reservoir portion reserves the liquid that is supplied to the liquid discharge head. The liquid injection portion allows a liquid injection container for injecting the liquid into the reservoir portion to be inserted in the liquid injection portion in a first direction. The liquid holding unit is provided at a position spaced apart from the liquid injection portion and is capable of holding the liquid. The liquid guide portion guides the liquid from the liquid injection portion to the liquid holding unit in a second direction intersecting with the first direction.

Liquid discharge apparatus and liquid storage container

An image recording apparatus includes a recording unit that records an image on a recording medium, a discharge unit configured to discharge the recording medium on which recording has been performed by the recording unit, a first conveying path for conveying the recording medium from the recording unit to the discharge unit, a heating unit configured to heat the recording medium on which recording has been performed by the recording unit and disposed on the first conveying path, and a second conveying path configured to branch off from the first conveying path at a branching portion between the heating unit and the discharge unit and configured to merge with the first conveying path between the recording unit and a stacking unit on the first conveying path.

Image recording apparatus with heating of recording medium on which recording has been performed and with branched conveying path

An inkjet printing apparatus includes a tank in which ink is contained; a print head for ejecting ink supplied from the tank to perform print operation; a supply flow path for supplying ink from the tank to the print head; a collection flow path for collecting ink from the print head to the tank; and a pump provided in the supply flow path or the collection flow path. The pump is driven, during print operation, at a first speed to circulate ink within a circulation path including the tank, the supply flow path, the print head, and the collection flow path, and the pump is driven, from a start of the ink circulation until a lapse of predetermined time period, at a second speed which is faster than the first speed.

Inkjet printing apparatus and control method of the same

Provided is an inkjet printing apparatus comprising: a print head that ejects ink; a tank that contains ink to be supplied to the print head; a floating body that floats on the liquid surface of the ink inside the tank; and an electrode pin that detects the level of the liquid surface inside the tank. The floating body includes an opening portion in which to insert the electrode pin, and a perimeter of the opening portion protrudes from a top surface side of the floating body.
