An ink jet recording apparatus includes an ink composition, an ink encasement in which the ink composition is encased, a recording head that ejects the ink composition, and a carriage configured to move the recording head back and forth. The carriage carries the ink encasement, with the ink encasement integrated with the carriage. The ink encasement has an ink fill port that opens and shuts as a port through which the ink composition is loaded. The ink composition contains a water-soluble dye and a polyhydric alcohol with a normal boiling point of 270° C. or above, with the percentage of the polyhydric alcohol being 26.0% by mass or less of the total amount of the ink composition.

A printer includes an ink tank, a print head performing printing by using ink in the ink tank; a light source irradiating an inside of the ink tank with light; a sensor detecting light incident from the ink tank during a period in which the light source emits light; and a background plate facing the light source and the sensor in the ink tank.

A wiping device includes a feeding portion having a feeding shaft, and configured to hold a band-like member, a pressing unit configured to allow a contact portion located in a contact region of the band-like member, to be brought into contact with a liquid ejecting portion, a winding portion having a winding shaft, and configured to be capable of performing a winding operation for winding the band-like member to move the contact portion in a movement direction, a brake mechanism configured to brake rotation of the feeding shaft, and a contact unit configured to contact the band-like member fed from the feeding portion and to apply tension to the band-like member, the contact unit being movable between an operating time position during the winding operation and a stop time position when the winding operation is not performed.

A memory includes: a first type storage area used in a one-time use period from when a liquid is filled into a cartridge to when consumption of the liquid is completed; and a second type storage area used in an entire use period of the cartridge, which is a set of one-time use periods, in which the first type storage area has a plurality of individual areas in which a different area is used in each one-time use period.

A printing apparatus that performs printing through an inkjet method includes an inkjet head and an ink supply system, where the ink supply system includes a pressure damper that is a pressure adjustment mechanism, a flow path that is a container-side flow path, and a connecting member in which a flow path that is a head-side flow path for flowing ink from the pressure damper to the inkjet head is formed, the pressure damper supplies ink adjusted to a pressure in a predetermined range lower than atmospheric pressure from an output port that is a pressure adjustment mechanism outlet to the flow path, and a flow path cross-sectional area of at least one part of the flow path in the connecting member is larger than a flow path cross-sectional area of the output port.

An image recording apparatus includes a controller configured to: (a) when a remaining amount of ink at the time of receiving a recording start instruction to start image recording on one recording medium is equal to or less than a predetermined amount and a calculated ink remaining amount is less than a required ink amount, not to start the image recording; and (b) when the remaining amount of ink at the time of receiving the recording start instruction is more than the predetermined amount, start the image recording according to the recording start instruction and, during the image recording according to the recording start instruction, when the remaining amount of ink is equal to or less than the predetermined amount and the calculated ink remaining amount is equal to or less than a threshold, interrupt the image recording.

Since ink is not heated at a protrusion connecting an ink supplying device and a print head chip or the like, the viscosity of the ink increases, and the fluidity may not be maintained in some cases. An inkjet printer 1 for solving the above problem includes an inkjet head 300 that ejects ink; a protrusion 310 provided to protrude from the inkjet head 300 and configured to circulate the ink to the inkjet head 300; and an ink flow path portion 6 that supplies the ink to the protrusion 310; where the ink flow path portion 6 includes an ink warming block 200 that heats the ink, and a conducting portion 210 that is formed in the ink warming block 200 itself or separately from the ink warming block 200 and through which heat from the ink warming block 200 is conducted is adjacently disposed outside the protrusion 310.

A drainage container configured to be attached and detached in an attachment/detachment direction to and from an apparatus including a discharge portion to discharge drainage and configured to store the drainage discharged from the discharge portion, includes: a housing that stores the drainage and includes an opening formed in an upper surface of the housing; an accepting portion that accepts the drainage discharged from the discharge portion; and a lid portion configured to open and close the opening, in which the lid portion takes on an open state to open the opening when the drainage container is attached to the apparatus, and the lid portion takes on a closed state to close the opening when the drainage container is detached from the apparatus.

A tank set includes: tanks arranged in a predetermined direction, each of the tanks being composed of a casing including: a liquid storage chamber defined by mutually opposing two surfaces and configured to store liquid; an inlet provided to inject the liquid into the liquid storage chamber; and a liquid outflow port through which the liquid flows out from the liquid storage chamber to a liquid-consuming unit. Each of the two surfaces extends in a direction intersecting the predetermined direction, and is at least partially composed of a film.

A liquid storage container is configured to supply a liquid containing a precipitating component to a liquid ejecting apparatus, including: a partitioning member configured to divide a liquid storage chamber in a direction intersecting a direction of gravitational force; a plurality of liquid storage chambers divided by the partitioning member; and communication flow channel units provided to the plurality of liquid storage chambers, respectively, and configured to introduce the liquid in the liquid storage chambers and to supply the liquid to the liquid ejecting apparatus.
