A liquid discharge head angle adjuster for individually adjusting inclination angles of a plurality of liquid discharge heads includes a plurality of array members and a plurality of array supports. The plurality of array members holds the liquid discharge heads. The plurality of array supports the array members. At least one of the array supports includes a first support, a second support, and a pressing member. The first support is disposed on one side in a direction in which one of the liquid discharge heads is rotated when an inclination angle of the one of the liquid discharge heads is adjusted. The first support supports a rotation fulcrum of one of the array members. The second support is disposed on a side opposite the first support, and supports another of the array member. The pressing member presses the rotation fulcrum against the first support.

There is provided a liquid ejecting apparatus including: a liquid ejecting head having 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; and a support configured to support the liquid ejecting head in an inclined posture in which the ejection surface is inclined with respect to a horizontal plane, in which the first nozzle row is positioned above the second nozzle row with respect to a vertical direction in a state where the support supports the liquid ejecting head in the inclined posture, and a thickening resistance of the second ink is higher than a thickening resistance of the first ink.

An inkjet printing device according to the present embodiment includes an alignment plate, a substrate positioned on one surface in a third direction of the alignment plate, and an inkjet head combined with the substrate, wherein the alignment plate includes a first position adjustor positioned on a first side surface in a first direction of the alignment plate, and a second position adjustor, a third position adjustor, a fourth position adjustor, a fifth position adjustor, and a sixth position adjustor positioned at a second side surface in a second direction of the alignment plate, and each of the position adjustors adjusts the position of the substrate.

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. A dynamic surface tension of the second ink is higher than a dynamic surface tension of the first ink. In the first posture, the first nozzle row is positioned above the second nozzle row with respect to a gravity direction.

A device for providing a marking arranged or arrangeable around an object includes: a mechanical interface for releasably or irreversibly mounting the device to a printer; a material interface for receiving a print medium, which is printed by the printer using a print head, as a printed product in a longitudinal direction; at least one eccentric supported at the material interface to be pivotable about a pivot axis; and at least one print head actuator for moving the at least one eccentric to a first pivot position and to a second pivot position different from the first pivot position to provide the marking originating from the printed product. The eccentric, in a state of the device mounted to the printer using the mechanical interface, moves the print head and the print medium towards each other into a printing position for printing the print medium when the eccentric moves.

A recording apparatus includes a head unit including a recording head and configured to move between a recording position where recording is performed on a medium and a retraction position away from a medium transportation path; a movement mechanism that moves the head unit; and a positioning portion configured to position the head unit at the recording position. A moment for rotating the head unit is produced by a force applied by the movement mechanism to the head unit and by a reaction force received by the head unit from the positioning portion. A unit pusher configured to apply, to the head unit, a force acting in a direction of canceling rotation of the head unit when the head unit is located at the recording position pushes the head unit in a direction intersecting with a moving direction of the head unit.

A liquid discharge apparatus includes: a liquid discharge head configured to discharge a liquid in a discharge direction onto a liquid application target; a stage configured to hold and move the liquid application target in a conveyance direction orthogonal to the discharge direction, a carriage on which the liquid discharge head is mounted; a guide holding the carriage movable in a main scanning direction orthogonal to each of the discharge direction and the conveyance direction; a pair of holders respectively holding sides of the guide in the main scanning direction; and multiple eccentric cams contacting the pair of holders, the multiple eccentric cams rotatable to move at least one of the pair of holders in at least one of the conveyance direction or the discharge direction to adjust a position of the carriage or the guide.

An image forming apparatus includes a liquid discharge head, an irradiation unit, a carriage, and a moving unit. The liquid discharge head discharges a liquid onto a recording medium. The liquid includes a metallic ink and a color ink. The irradiation unit irradiates the liquid on the recording medium with light. The liquid discharge head and the irradiation unit are mounted on the carriage. The moving unit alternately perform a main scanning movement and a sub-scanning movement. The liquid discharge head discharges the metallic ink in a region of the recording medium in a former main scanning movement and discharges the color ink in the region in which the metallic ink has been discharged, in a latter main scanning movement after the former main scanning movement. The irradiation unit irradiates the region in which the color ink has been discharged with the light.
