A control method of a liquid ejection device having an ejection unit, and a maintenance unit for maintaining the ejection unit, the ejection unit having a first head having a first nozzle configured to eject the liquid, and a second head having a second nozzle configured to eject the liquid and a third nozzle configured to eject the treatment liquid, the maintenance unit having a first receiving portion configured to receive the liquid, and a second receiving portion configured to receive the treatment liquid, and the control method includes executing a first flushing in which the liquid is ejected from the first nozzle to the first receiving portion, executing a second flushing in which the liquid is ejected from the second nozzle to the first receiving portion, and executing a third flushing in which the processing liquid is ejected from the third nozzle to the second receiving portion.

A recording device includes: a drive source; a driven portion having a driven gear; a drive transmission mechanism having a drive gear driven by the drive source and capable of swing between a first position where the drive gear is engaged with the driven gear and a second position where the drive gear is not engaged with the driven gear; and a regulating mechanism capable of swing between a regulating position where swing of the drive transmission mechanism is regulated and a non-regulating position where the swing of the drive transmission mechanism is not regulated. In the recording device, the regulating mechanism is capable of swing around a rotation axis of the driven gear.

A printing apparatus includes a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets; a recovery unit that recovers an ejecting condition of nozzles of the printing head; and a control unit that determines whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controls a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.

A liquid ejecting apparatus includes a switching valve having an outlet port and inlet ports, and switching, among channels, a channel to be communicated with the outlet port. The channels include: a first liquid-draining channel connecting a treatment liquid head and the switching valve, treatment liquid discharged to a treatment liquid cap flowing therethrough; a second liquid-draining channel connecting an ink head and the switching valve, ink discharged to an ink cap flowing therethrough; a first cleaning liquid-supplying channel connecting a cleaning liquid tank to the switching valve via the treatment liquid cap; a second cleaning liquid-supplying channel connecting the cleaning liquid tank to the switching valve via the ink cap; and a cleaning liquid bypass channel connecting the cleaning liquid tank to the switching valve not via the treatment liquid and ink caps.

Apparatuses, methods, and systems for localized printhead cleaning of a printing system are disclosed. A printing system performs a printhead health check operation for a printhead of the printing system. The printhead health check operation includes identifying and recording a set of nozzle defects within the printhead's nozzles, which can include any of clogs, misfires, and inconsistencies. Based on the printhead health check operation, the printing system determines a set of nozzle degradation metric values for the printhead, indicating the extent and nature of the nozzle defects. Using the set of nozzle degradation metric values, the printing system generates a set of actions for a carrier associated with the printhead. The set of actions adjusts at least one parameter of the cleaning device, such as its speed, motion profile, vacuum level, or wiper pressure, and defines a printhead actuation strategy. The printing system performs the cleaning of the printhead in accordance with the generated actions.

A maintenance method according to an embodiment of the present disclosure is a maintenance method for a recording apparatus including an ink jet head having a nozzle that ejects a water-based ink composition, the maintenance method including a leaving-to-stand step of performing leaving-to-stand with a nozzle surface in which the nozzle of the ink jet head is formed being in contact with an absorbing member containing a maintenance liquid.

An inkjet printing device. The inkjet printing device includes a printing table, a printhead, an ink supply module, and a cutter module. The printhead can print on a printing material disposed on the printing table. The ink supply module can supply ink to the printhead. The cutter module is configured to cut the printing material disposed on the printing table. The printhead includes a shell, a color ink printing module, and a white ink printing module. The shell defines a first through-opening on a surface of the shell facing the printing table. The color ink printing module and the white ink printing module are disposed opposite to the first through-opening, and are arranged in sequence in a conveying direction of the printing material. The inkjet printing device further includes a pressing mechanism. The pressing mechanism includes a second driving mechanism and a pressing roller.

A liquid discharge apparatus includes: a liquid discharge head having a discharge face having a nozzle from which a liquid is discharged to a medium; a carriage, to which the liquid discharge head is mountable, and reciprocally movable in a main-scanning direction; a guide supporting the carriage to guide the carriage to move in the main-scanning direction; a cap to contact and seal the discharge face of the liquid discharge head; a suction device connected to the cap; and a cap cleaner, supported and guided by the guide to move in the main-scanning direction, to drop a cleaning liquid to the cap.

An aqueous ink includes water, a solvent group A having a vapor pressure of 0.07 Pa or more at 25 C., a thickener, and a binder polymer. The solvent group A is present in the aqueous ink in a weight percent of 31.0 wt % to 55.0 wt % with respect to a total amount of the aqueous ink. The thickener is present in the aqueous ink in a weight percent of 13.0 wt % or less with respect to the total amount of the aqueous ink. The aqueous ink has a viscosity of 10 mPa.Math.s to 14 mPa.Math.s at 25 C.
