A head unit includes a recording head, a head-side frame, a unit frame, a first head mounting member, a second head mounting member, a head angle adjustment mechanism, and an urging member. The unit frame is configured to hold the recording head on both side surfaces of a main frame standing along a width direction orthogonal to a conveyance direction of a recording medium. The urging member is arranged on a side opposite to an opposing surface of the first head mounting member and the second head mounting member with respect to the main frame, and is configured to urge the head-side frame in a direction of separating away from the main frame, A counteraction of a pressing force that acts on the head-side frame from the urging member acts on the first head mounting member and the second head mounting member from the head-side frame.

A waste liquid collection unit is located over a print medium in a discharge direction of a liquid discharge head. The collection unit includes an absorber; a tray housing the absorber exposed to a nozzle surface of the head; and a pressing member to press the absorber toward a bottom surface of the tray. The pressing member includes a base material extending in an alignment direction of nozzles and end members connected to ends of the base material and displaceable to be biased to an inner wall surface of the tray in an axial direction when the pressing member is placed in the tray. The end members include a first fitting portion in a surface facing the inner wall surface. The tray includes a second fitting portion in the inner wall surface. The first and second fitting portions are fitted when the pressing member is placed in the tray.

A head cleaning device includes: a cleaning member that is long and comes into contact with nozzle surfaces of a first ejection head and a second ejection head arranged at intervals and cleans the nozzle surfaces; and a mover that moves, after completion of a previous cleaning and before start of a next cleaning, the cleaning member by a distance shorter than a path length from a portion that has cleaned the nozzle surface of the first ejection head to a portion that has cleaned the nozzle surface of the second ejection head up to the previous cleaning.

To enable highly accurate density unevenness correction while suppressing a reduction in productivity in printing accompanying correction value calculation for density unevenness correction. Based on an image obtained by scanning a chart including patches having uniform density for each tone value, a density characteristic of each nozzle is acquired. A non-ejectable nozzle that cannot eject ink normally is detected by analyzing a pattern for detecting the non-ejectable nozzle in the image obtained by scanning the chart. At the time of acquiring the density characteristic, the density characteristic is acquired based on a density measured value of an area of the image, which corresponds to a nozzle that is not detected as the non-ejectable nozzle.

An inkjet printing apparatus includes a printing unit having ejection parts, each configured to eject ink by using a piezoelectric element to be displaced in response to a change in electric potential. The inkjet printing apparatus also includes a circulation unit, a determination unit, and a control unit. The circulation unit executes ink circulation in a circulation path inclusive of the printing unit. The determination unit ejects the ink from each ejection part, detects residual vibration generated at an ejection part due to ink ejection, and determines an ejection state of ink ejection at the ejection part based on the detected residual vibration. The inkjet printing apparatus determines a printing state of ink ejection in the printing unit based on the ejection state. The control unit causes the determination unit not to make the ejection state determination in parallel with causing the circulation unit to execute the ink circulation.

A recording apparatus includes: a plurality of medium containing units that is provided along a vertical direction and contains a medium before recording; a liquid ejecting head that performs recording by ejecting liquid toward the medium; and at least one liquid containing unit that contains the liquid; wherein the plurality of medium containing units includes a first medium containing unit located at an uppermost position, and a second medium containing unit located below the first medium containing unit, a size of the first medium containing unit in a medium feeding-out direction, in which the medium is fed out, is smaller than a size of the second medium containing unit in the medium feeding-out direction, and the at least one liquid containing unit is provided above the second medium containing unit in such a way as to overlap with the first medium containing unit in the vertical direction.

Provided are an image forming device that always forms an image with an optimum treatment quality, and a manufacturing method of a printed material. An image forming device includes a transport unit that transports a recording medium in a transport direction, a printing unit that applies an ink to a printing surface of the transported recording medium to perform printing, a treatment unit that performs treatment on the transported recording medium, and a movement unit that changes a distance between the printing unit and the treatment unit in the transport direction, in which the distance is controlled based on at least one information of information on a transportation speed of the recording medium in the transport unit, information on an applied amount of the ink in the printing unit, or information on a surface state of the printing surface of the recording medium.

A recording device, when recording is performed on a predetermined type target recording medium stored in a storage unit, drives a surface potential adjustment unit so that a surface potential is a positive potential within a predetermined range. By configuring such a recording device, it is possible to suppress adhesion of ink to an ejecting unit, and occurrence of an ink ejection failure can be suppressed.

A liquid ejecting apparatus includes a liquid ejecting head that has an ejection surface including a first nozzle row configured to eject a first ink and a second nozzle row configured to eject a second ink. The liquid ejecting head is configured to be held in a first posture in which the ejection surface is inclined with respect to a horizontal plane. The dynamic surface tension of the first ink is higher than the dynamic surface tension of the second ink. In the first posture, the first nozzle row is positioned above the second nozzle row with respect to a gravity direction.

A first frame holds a platen. A second frame holds a head. When the second frame is at a first position, the head faces the platen. When the second frame is at a second position, the second frame is positioned farther away from the first frame than when the second frame is at the first position. At the second position, the head is positioned farther away from the platen than when the second frame is at the first position. A head lifter is held by the second frame. At the first position, the head lifter moves the head with respect to the second frame between a printing position and a separate position. At the printing position, the head ejects liquid toward a medium supported by the platen. At the separate position, the head is farther away from the platen in an intersecting direction than at the printing position.
