A liquid ejecting apparatus includes: a liquid ejecting head configured to eject liquid contained in a liquid container; a display portion configured to display information; a remaining amount detection portion configured to detect that a remaining amount of the liquid contained in the liquid container becomes less than a threshold value; and a control portion configured to control display of the display portion, in which the control portion causes the display portion to display a calculation remaining amount calculated based on an initial amount of storage of the liquid contained in the liquid container, a total discharge amount of the liquid discharged from the liquid ejecting head, and a correction amount corresponding to a use environment.

Liquid ejecting apparatus and control method of liquid ejecting apparatus

A control method for a liquid ejecting system provided with a liquid ejecting apparatus including a liquid ejecting portion for ejecting a liquid and an inputting apparatus including a data inputting portion through which data can be inputted includes a specific data detecting process that detects whether or not input data inputted to the data inputting portion is specific data which is other than liquid ejection data for causing a liquid corresponding to an image to be formed on an ejection target medium to be ejected from the liquid ejecting portion and which is determined in advance as data for prompting an ejection inspection; and a nozzle inspecting process that, in the case where the specific data is detected in the specific data detecting process, causes a nozzle inspecting portion to perform the ejection inspection.

Control method for liquid ejecting system and liquid ejecting system

An attachment is mountable on a carriage in place of a liquid container that contains liquid and that is mounted on the carriage having a liquid jet head for jetting liquid, so that the attachment can supply liquid introduced from outside to the liquid jet head. The attachment has a pressure control means provided in a flow passage which is formed in an attachment body and through which the liquid introduced from the outside is supplied to the liquid jet head.

Attachment and attachment system

An ink jet printer includes an attachment detection portion that detects an attachment of an ink storage member that retains an ink in an absorber contained in the ink storage member itself; an ink jet recording head that ejects an ink flown in from the ink storage member; and a control circuit that controls ink ejection performed by the ink jet recording head. The control circuit is configured to, upon detection, by the attachment detection portion, of an attachment of the ink storage member to be newly used, perform control so as to cause a first operation mode to be set, and thereafter, perform control so as to cause the first operation mode to be switched to a second operation mode, upon satisfaction of a condition in that a total discharge amount of an ink ejected in the first operation mode reaches a prescribed amount. Further, a per-unit-time discharge amount of an ink ejected in the first operation mode is set so as to be smaller than a per-unit-time discharge amount of an ink ejected in the second operation mode.

Ink jet printer and control method therefor

There is provided a capping device having a bottomed box-shaped cap having an opening at one of ends of short side walls and long side walls formed in a ring shape and a bottom portion on the other side, the bottom portion is formed with a waste liquid disposal port configured to discharge liquid flowed therein from the opening and a rib extended so as to connect two opposing wall surfaces of the long side walls at a position overlapping at least partly with the waste liquid disposal port two-dimensionally when viewed from the side of the opening, and the rib including a communication hole configured to penetrate in the width direction intersecting the direction of extension of the rib and communicate with the waste liquid disposal port.

Capping device and liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member.

Liquid ejecting apparatus and maintenance method for a liquid ejecting apparatus

A second sealing film Fis thermally bonded onto a leading end portion Rof an ink lead-out memberof an ink pack and an annular projecting portion Rprovided on an ink casing. Thereby, a gap D produced between the ink lead-out memberand the ink casingcan be closed from outside the ink casing. Accordingly, the airtightness of a space S in the ink casingis kept, thus making it possible to raise the pressure in the space S and generate such a force as to crush the ink pack.

Liquid container

A liquid supplying mechanism includes a flow channel forming member that has a base having a plate-like shape on which an upstream portion of a plurality of liquid supplying flow channels are formed so as to supply ink to each of a plurality of liquid ejection heads that are assembled to a liquid ejection head unit, and a plurality of connection members in a tubular shape that extend from one side of the of the base so as to form a downstream portion of the flow channels that individually communicate with the upstream portion of the respective liquid supplying flow channels and are disposed such that the distal end of the connection members correspond to the positions of the connection holes that are formed on the respective liquid ejection heads.

Liquid supplying mechanism and liquid ejecting apparatus

A fluid ejecting apparatus includes a fluid containing portion, a fluid discharging portion, a flow passage forming portion and a valve mechanism. The fluid containing portion contains fluid. The fluid discharging portion discharges the fluid. The flow passage forming portion forms a fluid flow passage that extends from the fluid containing portion to the fluid discharging portion. The valve mechanism is able to open or close the fluid flow passage. The fluid ejecting apparatus is placed in an initial state before an initial use of the fluid ejecting apparatus, wherein fluid is contained in the fluid containing portion and at least portion of the fluid flow passage from a position of the fluid containing portion to a position of the valve mechanism is filled with the fluid and the fluid flow passage is closed by the valve mechanism.

Fluid ejecting apparatus and fluid filling method of fluid ejecting apparatus

A second sealing film is thermally bonded onto a leading end portion of an ink lead-out member of an ink pack and an annular projecting portion provided on an ink casing. Thereby, a gap produced between the ink lead-out member and the ink casing can be closed from outside the ink casing. Accordingly, the air tightness of a space in the ink casing is kept, thus making it possible to raise the pressure in the space and generate such a force as to crush the ink pack.
