A print device includes a processor and a memory. The memory storing computer-readable instructions which, when executed by the processor, perform processes. The processes include covering processing controlling a cap into a covering state in which the cap covers a nozzle. The processes include first purge processing purging, in a state in which the cap is in the covering state and a supply valve is closed, an ink from the nozzle by operating a pump at a first rotation speed. The processes include injection processing injecting, after the first purge processing and in a state in which the cap is in the covering state and the supply valve is open, the cleaning liquid into the interior of the cap by operating the pump at a second rotation speed to cause the cleaning liquid to soak a nozzle face.

A pressure adjusting device includes a housing with a cylinder. A piston moves within the cylinder in an axial direction. A pulse motor is fixed to the housing. A switch provided on a surface of the cylinder is actuated by movement of the piston in the cylinder in the axial direction. The switch includes a fixed contact point and a moveable contact point. The piston presses the movable contact point to abut against the fixed contact point when the piston moves from a position other than the initial position to the initial position so that the movable contact point electrically contacts the fixed contact point.

A fabric printing device includes a printing surface for holding a fabric to be printed and an ink nozzle array movable between a print position and a standby position. The ink nozzle array is located over the printing surface when in the print position and includes a plurality of ink nozzle groups. Each ink nozzle group is configured to spray a different color ink than an adjacent ink nozzle group. The fabric printing device also includes a recycle ink tray defining a plurality of partitioned ink pools, each ink pool associated with one of the plurality of ink nozzle groups. The ink nozzle array is positioned over the recycle ink tray when in the standby position such that substantially all of the ink sprayed from a particular ink nozzle group is received in a respective partitioned ink pool and isolated from ink in an adjacent partitioned ink pool.

An inkjet printing and an inkjet printing method are provided. The inkjet printing device includes a stage comprising a substrate mounting part configured to receive a target substrate mounted thereon, a print head unit located above the stage and configured to spray an ink including a plurality of particles, and a suction device located at a side of the substrate mounting part and configured to generate negative pressure thereon.

Disclosed is an inkjet head cleaning device comprising: a body; an ejection part formed in the body, and configured to eject a cleaning liquid to a nozzle surface of a head; and, a suction part formed in the body, and configured to suck the cleaning liquid ejected from the ejection part and used for cleaning the nozzle surface of the head, and foreign substances separated from the nozzle surface of the head; and wherein the ejection part comprises, a perpendicular passage through which the cleaning liquid flows and a discharge end at the end of the perpendicular passage and configured to guide the cleaning liquid to eject toward the suction part.

An ink jet printing method includes an application step of ejecting a coloring ink composition functioning to color a printing medium through an ejection opening of a first ink jet head to apply the coloring ink composition onto a printing medium, and an application step of ejecting a non-coloring composition different from the coloring ink composition through an ejection opening of a second ink jet head to apply the non-coloring composition onto the printing medium. The coloring ink composition is circulated through a circulation path connected to the first ink jet head after being fed into the first ink jet head and before being ejected through the ejection opening of the first ink jet head. The non-coloring composition is not circulated through a circulation path after being fed into the second ink jet head and before being ejected through the ejection opening of the second ink jet head.

A print device includes a head, a cap, a suction portion, an absorption member, and a plate-shaped member. The head has an ejection surface. The ejection surface has a plurality of nozzles formed in the ejection surface and is directed in a predetermined direction. The cap has a frame-shaped wall portion and a suction opening. The suction portion is connected to the inside of the cap via the suction opening. The absorption member is arranged in a position surrounded by the frame-shaped wall portion and is configured to absorb liquid. The plate-shaped member is surrounded by the frame-shaped wall portion and is arranged in a position facing the absorption member. The plate-shaped member is extending along an inner end surface of the frame-shaped wall portion and has a hole.

Provided is an inkjet recording apparatus that reduces clogging of nozzles, while at the same time avoid a decrease in productivity of the recording medium, and reduces situations in which the recording medium becomes stained due to the staining of opening portions and splashing due to ink ejected during flushing. A conveyor belt of the inkjet recording apparatus has a plurality of opening portion groups. The control unit determines the pattern of the plurality of opening portion groups used for flushing in one cycle of the conveyor belt according to the size of the recording medium. The control unit causes the recording medium to be supplied from the recording medium supply unit between the plurality of opening groups arranged in the conveying direction in the above pattern on the conveying belt and at positions separated from the opening portion groups by a specific distance or more.

A liquid ejection device includes an ejection head, a cap configured to cover the nozzle, a first liquid receiver including a first receiving surface and a discharge portion connected to the first receiving surface. The liquid ejection device includes a second liquid receiver including a second receiving surface positioned under the discharge portion. One of the first liquid receiver and the second liquid receiver has an engagement portion, and the other of the first liquid receiver and the second liquid receiver has an engaged portion. A play between the engagement portion and the engaged portion is smaller than a distance between both ends of the second receiving surface in the direction parallel to the second receiving surface.
