A posture adjusting apparatus includes: an ink ejector that has a detachable inkjet head that ejects ink; and a posture adjuster for adjusting a posture of the ink ejector. The ink ejector includes a head fixing member to/from which the inkjet head is attached and detached, and is movable between a first position where an image is formed on a recording medium by the inkjet head and a second position where the inkjet head is attached and detached, and the posture adjuster allows adjustment of an angle of the head fixing member in the second position.

A head assembly includes a base member, a recording head, a coupling member, and a pressing member. The recording head ejects ink. The coupling member couples the recording head to the base member. The pressing member is in contact with a first surface of the recording head. The coupling member includes an urging member that urges a second surface of the recording head toward the first surface of the recording head. The second surface of the recording head is a surface of the recording head on an opposite side from the first surface.

A liquid discharge device includes a liquid discharge head to discharge a liquid, a head holder to hold the liquid discharge head, a sub-carriage to hold the head holder, a carriage to hold the sub-carriage and move in a main scanning direction, an adjuster supported by the sub-carriage, and a guide to guide the sub-carriage to be movable in a vertical direction. The carriage includes a reference shaft extending in the main scanning direction, the reference shaft supports the sub-carriage via the adjuster and positions the sub-carriage in the vertical direction, the adjuster adjusts an inclination of the sub-carriage with respect to the reference shaft, the sub-carriage includes a sub-reference shaft extending in parallel with the reference shaft, and the guide allows the sub-reference shaft to move in the vertical direction while restricting a movement of the sub-reference shaft in a sub-scanning direction perpendicular to the main scanning direction.

A printer includes a transport unit, a line head, and a head moving unit. The transport unit supports a medium during transport. The line head performs recording on the medium that is disposed so as to face the transport unit at one or more recording positions of recording on the medium. The head moving unit moves the line head to one or more retreat positions away from the transport unit with respect to the recording position. In addition, the head moving unit moves the line head in a B direction intersecting both an X direction and a Z direction.

A printing apparatus includes: a head having a discharge surface in which a discharge port is opened, a pressure chamber which communicates with the discharge port, and an actuator which is configured to change a volume of the pressure chamber; a carriage configured to move the head in a scanning direction; a conveyor configured to move an object in a conveyance direction crossing the scanning direction; a posture changing mechanism configured to change a facing posture of the head with respect to the object; and a controller configured to control the actuator, the carriage, the conveyor and the posture changing mechanism, based on image data, to execute alternately and repeatedly a scanning operation and a conveying operation.

A device for use in organic vapor jet printing (OVJP) and similar arrangements includes a print head movable in more than one degree of freedom with sufficient thermal insulation that there is little to no movement in the Z direction. One or more sensors may be used to monitor and adjust the distance between the substrate and the print head.
