  • Patent number: 9682583
    Abstract: 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.

  • Patent number: 9375918
    Abstract: 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.

  • Patent number: 8857949
    Abstract: 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.

  • Patent number: 8668317
    Abstract: A second sealing film F2 is thermally bonded onto a leading end portion R1 of an ink lead-out member 32b of an ink pack and an annular projecting portion R2 provided on an ink casing 31. Thereby, a gap D produced between the ink lead-out member 32b and the ink casing 31 can be closed from outside the ink casing 31. Accordingly, the airtightness of a space S in the ink casing 31 is kept, thus making it possible to raise the pressure in the space S and generate such a force as to crush the ink pack.

  • Patent number: 8128210
    Abstract: 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.

  • Patent number: 7997703
    Abstract: The invention provides a liquid container for storing liquid to be supplied to a liquid consuming apparatus. The liquid container is constructed such that pressurized fluid is sent to its inside so that the liquid in the inside is delivered to the outside. The liquid container includes a container body which stores the liquid in its inside. The container body includes a pressurized fluid introduction port for introducing the pressurized fluid to the inside and a liquid delivery port for delivering the liquid to the outside. A detection unit is provided in the container body and outputs an output signal which is changed in accordance with a change in pressure of the liquid in the inside of the container body.

  • Patent number: 7967428
    Abstract: Since a bypass flowing passage which communicates with the inside of a bag part not through a second valve mechanism is provided for an outlet part, ink can be filled from the outlet part into the bag part in spite of the existence of the second valve mechanism. Further, after an empty ink pack has been housed in an inner case, the ink is filled into the ink pack. Therefore, when a first seal film is welded to the inner case, since the bag part is not bulky, the ends of the bag part are caught in a cartridge case. Therefore, the maximum amount of ink for the inner volume of the cartridge case can be filled. Further, since a bypass flowing passage is blocked after the ink has filled into the ink pack, contamination of air bubbles into the bag part through the bypass flowing passage is prevented.
