An inkjet recording device includes an operating state acquisition unit that acquires parameter values indicating an operating state of the inkjet recording device, which includes at least one a pressurization state, a charge state, a deflection state, and a recovery state, a display unit that displays a reception screen for receiving a command to generate a two-dimensional code from a user, and a code generation unit that generates the two-dimensional code by encoding a parameter value constituting a parameter set of a predefined type among the parameter values acquired by the operating state acquisition unit when the generation command is received via the reception screen of the display unit. The display unit is configured to display the two-dimensional code generated by the code generation unit.

A recording device is a recording device receiving liquid supplied from a liquid accommodation unit, and includes a recording unit configured to eject the liquid onto a transported medium, a support unit configured to support the medium at a position facing the recording unit, a first side frame and a second side frame that are configured to support one end side and the other end side of the support unit, a coupling frame configured to couple the first side frame and the second side frame, and a holding unit configured to hold the liquid accommodation unit. The coupling frame is located below the support unit, and the holding unit is located between the support unit and the coupling frame and between the first side frame and the second side frame.

A spittoon system for a printing mechanism includes a reservoir elongated in a longitudinal direction and having a bottom part. The reservoir receives printing fluid residue spit from a print-head onto a first zone of the reservoir. The spittoon system further includes a cleaning element arranged inside the reservoir to transfer, by sliding along the longitudinal direction of the reservoir, the received printing fluid residue from the first zone to a second zone. The second zone includes a drain outlet to drain the printing fluid residue from the reservoir.

At least some issues such as making it difficult for liquid to leak to the outside, making it easy for liquid contained in a buffer chamber to return to a liquid storage portion, and suppressing an increase in the installation area of the entirety of a printing apparatus is achieved. A liquid supply apparatus includes a liquid tank that contain a liquid, a connection channel member connected to the liquid tank, and a buffer tank that is configured separately from the liquid tank, is connected to the liquid tank via the connection channel member, and is communicated with the atmospheric air. The liquid tank includes a liquid storage chamber provided inside of the liquid tank, and a liquid inlet portion for injecting liquid into the liquid storage chamber. The buffer tank has a buffer chamber, bottom face of the buffer chamber is positioned at a position higher than a maximum liquid level of the liquid tank.

A printing device can be used to print on a surface of a workpiece made at least partly of wood, a wood material, synthetic material, composite material or the like. The printing device can include an ink supply device holding a printing ink and an ink feed system by means of which the printing ink can be supplied to a print head in order to carry out a printing process The device can also include a flushing device that can flush the ink feed system or the print head with a flushing liquid for a printing ink change.

An inkjet recording apparatus includes a recording head, a waste ink container, and a suction mechanism. The waste ink container has a plurality of receiving ports to receive ink ejected from the recording head, a suction port disposed at a position apart from each of the plurality of receiving ports, and a plurality of suction air passages connected to the plurality of receiving ports, respectively, so as to communicate between a destination receiving port and the suction port. The plurality of suction air passages are each bent between the destination receiving port and the suction port, and at least two suction air passages join at a predetermined position between the destination receiving port and the suction port.

An inkjet recording apparatus includes a head unit, a wipe unit, and a control part. The head unit is provided with a nozzle surface on which a plurality of ink ejection ports is opened downward. The wipe unit performs a wiping operation in which a blade is moved along the nozzle surface while applying a cleaning liquid to the nozzle surface to wipe the nozzle surface. The control part controls the head unit and the wipe unit to perform a first maintenance operation to perform the wiping operation and a second maintenance operation to perform the wiping operation after the ink is pushed out from the nozzle surface. In the second maintenance operation, the cleaning liquid applied to the nozzle surface is suppled firstly, then the ink is pushed out from the nozzle surface, and then wiping operation is performed.

An ink-jet recording apparatus includes: a recording head; a waste-ink container; and a suction mechanism, the waste-ink container including a plurality of catching ports that are configured to catch ink, a suction port that is connected to the suction mechanism, and a plurality of suction airflow paths that are connected respectively to the plurality of catching ports, and that are configured to allow suction airflow to pass through the plurality of suction airflow paths by communicating the plurality of catching ports being connection destinations and the suction port with each other, the suction airflow being generated by driving of the suction mechanism, an at least one suction-airflow path among the plurality of suction airflow paths including a bent portion that is bent from a first direction into a second direction at a point between a corresponding one of the plurality of catching ports and the suction port.

A printing apparatus performs a printing operation where mist that is generated in inkjet printing is efficiently collected. Specifically, a fan is rotated during a mist collection operation at a maintenance operation with a rotating speed that is greater than the rotating speed of the fan during printing.

There is provide an ink-jet recording apparatus including: an ink containing a resin dispersion type pigment; an ink-jet head configured to discharge the ink; an absorber which is arranged in an area facing a discharge surface of the ink-jet head, and which is configured to absorb the ink discharged from the ink-jet head; and a liquid agent which contains a water-soluble organic solvent, and which is absorbed in the absorber, wherein a surface tension of an aqueous solution containing the liquid agent at concentration of 5% by weight is not more than 50 mN/m; and a blending percentage by weight of the water-soluble organic solvent in the liquid agent is not less than seven times a blending percentage by weight of the resin dispersion type pigment in the ink.
