A device for adjusting a printing head includes a step-by-step switching mechanism, an actuator for shifting the step-by-step switching mechanism, and a locking disk supported for rotation. A first shifting tongue is provided for incrementally rotating the locking disk in a first direction of rotation. The first shifting tongue has two elongated holes for guidance purposes, one of which has a lateral recess. It is thus possible to adjust printing heads with a high degree of accuracy while saving time and costs. The device is preferably implemented in industrial inkjet printing.

An inkjet print module includes: a printhead having first and second rows of print chips, the printhead having 180 degree rotational symmetry about a print axis parallel to a direction of droplet ejection; a cradle for removably receiving the printhead; and control circuitry for distributing data signals to the printhead via first and second data paths of the inkjet print module. The cradle is configurable for receiving the printhead in first and second printhead orientations relative to the print module, the second printhead orientation being rotated 180 degrees about the print axis relative to the first printhead orientation. The control circuitry is configurable to invert distribution of the data signals between the first and second data paths.

A printing system comprises a sub-frame (5), a print module (8) with printheads (27), a first support unit (30) that is connected to the sub-frame (5), in particular movable in a displacement direction (z) relative to the sub-frame, a substrate holder (2) for supporting a substrate (3), and a positioning mechanism for moving the print module relative to the first support unit to and from a print position. A set of positioning parts (34-36) and positioning references (14-16) is provided that form part of or are connected to the print module (8) respectively the sub-frame (5). The positioning parts (34-36) are engageable with corresponding ones of the positioning references (14-16) for aligning the print module (8) relative to the sub-frame (5) when moved into its print position. The positioning mechanism comprises one or more four-bar linkage mechanisms (32) acting between the print module (8) and the first support unit (30).

A printing apparatus includes a printhead on a movable carriage; an operating unit operating by a driving force of a driving source; a transmitting unit being displaced by the driving force between a position where the transmitting unit transmits the driving force to the operating unit and a non-transmitting position; a movable member arranged on a moving path of the carriage; a restricting member being displaced, in coordination with a displacement of the movable member, between a position where the displacement of the transmitting unit is restricted and a non-restricting position; and a selecting member provided between the movable member and the restricting member. The selecting member is displaced between a position where the movable member and the restricting member are coordinated with each other by the selecting member and a non-coordinating position.

A digital decorator machine for the decoration of products (P), including a support frame, at least one conveyor, for transporting the products (P) to be decorated along an advancement direction, at least one decoration element, associated with said support frame and positioned above said conveyor, said at least one decoration element including respective print heads provided with ejector nozzles for a fluid to be dispensed on the surface of the products (P) to be decorated, and a casing within which at least one support is housed that is integral with said heads. The support is movable, with respect to said casing, between an upper inactive position and a lower operating position, in which said heads are correctly spaced with respect to the surface of the products to be decorated (P).

A liquid discharge apparatus includes a liquid discharge head to discharge liquid to a medium to form liquid surface on the medium, an irradiator to radiate active energy rays onto the liquid surface, a carriage mounting the liquid discharge head and the irradiator, a scanner to scan the carriage in a main scanning direction, a height adjuster to adjust an irradiation distance between the irradiator and the liquid surface by relatively moving the carriage and the medium, a conveyor to move the medium and the carriage relatively in a sub-scanning direction perpendicular to the main scanning direction, and control circuitry to control the irradiator to irradiate the liquid surface with the active energy rays while scanning the carriage in the main scanning direction.

There is provided a recording device including a transport section that transports paper along a support surface; a recording section; a determination region setting section; a liquid volume ratio calculation section; a determination section; and a recording position adjustment section that, when the determination section determines that the average value is larger than the threshold, adjusts a distance of the recording section from the support surface to a distance which is longer than a case in which the average value is not larger than the threshold.

Provided herein is a printer comprising a printing assembly. The printing assembly comprises a printhead bracket fixedly attached to the printer, a printhead that defines a groove, the printhead aligned at a first alignment, an alignment adjuster fastened between the printhead bracket and the printhead, and a plurality of fasteners operatively engaged with the alignment adjuster.
