A printer comprising a printhead configured to selectively cause a mark to be created on a substrate provided adjacent to the printer, the printhead having a first configuration in which the printhead is spaced apart from the printing surface and a second configuration in which the printhead is configured to press the substrate against a printing surface during a printing operation. The printer further comprises a printhead drive assembly configured to cause movement of the printhead towards and away from the printing surface between the first and second configurations, the printhead drive assembly comprising a permanent magnet and an electromagnet. When the electromagnet is in a first condition, an attractive magnetic force is generated between the permanent magnet and the electromagnet, and when the electromagnet is in a second condition, a repulsive magnetic force is generated between the permanent magnet and the electromagnet, each of said attractive and repulsive magnetic forces being configured to one of urge the printhead away from and towards the printing surface. The printhead drive assembly is configured such that, when the printhead is in each of the first and second configurations, it is retained in that configuration by the printhead drive assembly when the electromagnet is in the first condition, the printhead being retained in one of the first and second configurations by said attractive magnetic force generated between the permanent magnet and the electromagnet.

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.

The disclosure relates to a method for printing on containers, wherein the containers rotate in a transport carousel, and a co-rotating printing station is assigned to each container on the transport carousel, and the containers are finally printed by the respective printing station having a single print head having a maximum of two ink supplies only in a partial region of the printable container height. The disclosure further relates to a direct printing machine for carrying out the aforementioned method.

Provided is an inkjet printer capable of suppressing variations in landing positions of inks ejected from a plurality of inkjet heads mounted on a carriage for each inkjet head. In this inkjet printer, a plurality of inkjet heads 3 are mounted on a carriage. This inkjet printer includes at least one of a first inclination adjustment mechanism (13) for adjusting the inclination of each of the inkjet heads (3) with respect to the carriage in a pivoting direction having a sub scanning direction as an axial direction of pivoting, and a second inclination adjustment mechanism (14) for adjusting the inclination of each of the inkjet heads (3) with respect to the carriage in a pivoting direction having a main scanning direction as an axial direction of pivoting.

A printer comprising a printhead configured to selectively cause a mark to be created on a substrate, a first motor coupled to the printhead and arranged to vary the position of the printhead relative to a printing surface against which printing is carried out to thereby control the pressure exerted by the printhead on the printing surface, and a controller arranged to control the first motor. The controller is arranged to control the magnitude of current supplied to windings of the first motor so as to cause a predetermined pressure to be exerted by the printhead on the printing surface.

There is provided an inkjet recording apparatus includes a conveyance unit, a head unit, an attachment member, a fixing member, and a support member. The conveyance unit conveys a recording medium on an outer circumferential curved surface of a cylindrical conveyance drum rotating around a cylindrical shaft. The relative position of the attachment member to the cylindrical shaft is fixed. The head unit has a nozzle ejecting ink and is attached to the attachment member such that the outer circumferential curved surface faces an opening of the nozzle across a predetermined relative distance. The fixing member fixes a fixing portion in the head unit to the attachment member. The fixing portion is between a center of gravity of the head unit and the cylindrical shaft. The support member supports the fixed head unit by applying force which disturbs rotation of the head unit.

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.
