A liquid cartridge configured to be inserted into a cartridge attachment section includes: a cartridge body having a liquid storage chamber, and a liquid supply portion configured to supply the liquid stored in the liquid storage chamber to an outside. The liquid supply portion includes: a front end face facing frontward, an outer peripheral surface extending rearward from the front end face, and at least one guide provided at the outer peripheral surface. Each of the at least one guide is guided by corresponding at least one projection of the cartridge attachment section during attachment of a liquid supply tube of the cartridge attachment section to the liquid supply portion at a time of attachment of the liquid cartridge to the cartridge attachment section. Each of the at least one guide includes: a first guide portion, and a second guide portion.

Examples of a fluidic interface for a printing device are described. In some examples, the fluidic interface may include a shutter lock to prevent movement of a shutter covering a needle to engage a print substance supply. In some examples, the fluidic interface may also include a supply key opening to receive a supply key of the print substance supply that engages the shutter lock to permit movement of the shutter to expose the needle.

A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

A liquid supply apparatus includes a liquid storage tank in communication with a liquid ejecting head that ejects liquid and a cartridge configured to be detachably provided to the liquid storage tank. The liquid storage tank includes an atmosphere communication portion in communication with the atmosphere and a first connecting portion that, in a state where the cartridge is attached to the liquid storage tank, enables the cartridge to be in liquid communication with the liquid storage tank. The liquid storage tank also includes a second connecting portion that, in the state where the cartridge is attached to the liquid storage tank, is connected to the cartridge so as to be liquid-tight with the cartridge and enables the cartridge to be in gaseous communication with the atmosphere communication portion.

[Object] To appropriately warm ink.

[Solving Means] An inkjet printer 1 includes an inkjet head 3 and an ink warming mechanism 12. The ink warming mechanism 12 includes a warming part main body 21; an ink flow path 21a formed inside the warming part main body 21; a heater 22 that is attached to the warming part main body 21 and heats the warming part main body 21; a warming part temperature sensor 23 that is attached to the warming part main body 21 and detects a temperature of the warming part main body 21; and a heater controller 4 that controls the heater 22. The heater controller 24 controls the heater 22 based on the detection result of the warming part temperature sensor 23 so that the temperature of the warming part main body 21 becomes a predetermined reference temperature.

A recording apparatus includes: a housing; a recording section that performs a recording operation on a medium and is disposed inside the housing; a storage section that stores the medium; a transport route along which the medium is transported; a transport section that transports the medium; a reading section that reads an original sheet and is positioned higher than the recording section; a supply section that supplies the original sheet to the reading section; and a supply route through which the original sheet passes. Each of the supply and transport routes is formed at substantially right angles to a width of the housing. The transport route has a curved section in which the medium is turned over. The reading section is positioned behind the recording section in a depth direction from the front to rear surface of the housing.

A liquid refill container for refilling a liquid discharge apparatus with liquid includes a liquid storage portion, a pouring portion, and a cap portion. The liquid storage portion is made of a metal and contains liquid. The pouring portion is removeably connected to the liquid storage portion and has an outlet for pouring the liquid. The cap portion is removeably attached to the pouring portion and covers the outlet.

A liquid container refillable with liquid to be supplied to a printer includes a bag; a liquid supplying port member having a liquid supplying port; a liquid supply flow passage provided inside the liquid supplying port member; a liquid filling flow passage branching off from the liquid supply flow passage; and a communication port provided inside the liquid supplying port member and being in communication with the liquid filling flow passage and facing an internal surface of the bag. The bag is fixed to the liquid supplying port member such that a gap is formed between the bag and the peripheral portion of the communication port due to a flow of the liquid from the liquid supply flow passage to the liquid filling flow passage, the gap being in communication with the liquid containing portion through the communication port.

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.

An image-recording apparatus includes: a first tank defining a first storage chamber; a second tank defining a second storage chamber; a conveying mechanism for conveying sheets along a conveying path extending in a depthwise direction and a widthwise direction perpendicular to a vertical direction and the depthwise direction; and a recording head including a nozzle. Liquid in the first storage chamber is supplied through a communication port to the second storage chamber and then to the recording head through a liquid outlet port. The second storage chamber is positioned further in a first depthwise direction relative to the nozzle and further in a first widthwise direction relative to the conveying path. A volume of a prescribed space above a liquid level equal to a height of the communication port in the second storage chamber is greater than that of a liquid channel between the liquid outlet port and the nozzle.
