A modular inkjet printhead assembly including a plurality of printhead modules mounted on alternating sides of a central rail assembly. The rail assembly includes a beam and a rod attached to a side of the beam. The printhead modules include a jetting module having an array of nozzles, a first alignment tab having a first alignment datum and a second alignment datum, a second alignment tab having a third alignment datum and a fourth alignment datum, a rotational alignment feature including a fifth alignment datum, and a cross-track alignment feature including a sixth alignment datum. Portions of the alignment tabs of the jetting module are adapted to fit within corresponding notches in the beam. Each alignment datum on the printhead modules engage with corresponding alignment features on the rail assembly to position the printhead modules such that the jetting modules are tilted away from the beam.

A device for use in 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.

A method of wiping a plurality of printheads positioned in a staggered overlapping arrangement across a width of a media feed path, each printhead having a respective wiper associated therewith. The wipers for neighboring printheads are moved in opposite directions with respect to each other.

A print-head module for a single-pass inkjet printer contains a housing component with a transverse bracket which extends in the X-direction and on which a number of print heads are arranged which are adjusted positionally with respect to at least one reference position. A load-bearing frame with a supporting device is provided for supporting the load-bearing frame. The housing component is mounted on the load-bearing frame such that it swings about a pendulum axis. Furthermore, a single-pass inkjet printer has at least one print-head module of this type. The inkjet printer contains a frame construction with a support, on which the at least one print-head module is placed by use of the supporting device.

The present invention relates to an ink-jet print heads protecting system in a digital printing machine, wherein the module comprises a chassis (1), rollers (2), and a plurality of digital printing units (10), each with a bridge (11) with guides (12) and a sliding carriage (13) with ink-jet print heads (14), one part of each guide overlapping the band and another part projecting beyond the band path, the carriage being movable between the printing and maintenance positions; and in that each bridge is attached to the chassis by a position adjustment device (20) and an articulation (25) that are spaced apart or by two position adjustment devices (20) that are spaced apart.

An inkjet printing apparatus, comprising: a carriage to move in a 1st direction; a recording head; an ink reservoir; an ink receiver; and a waste liquid reservoir configured to be connected to the ink receiver to let the ink move between the ink receiver and the waste liquid reservoir, wherein: the ink reservoir is disposed not to overlap with the carriage in a 2nd direction perpendicularly intersecting with the 1st direction and an up and down direction, and at least a part of the ink reservoir is disposed at a position outside of a moving range of the carriage in the 1st direction; and in the 1st direction, the waste liquid reservoir is disposed to overlap with the ink reservoir and is disposed at a position outside of the moving range of the carriage.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system includes a treatment unit including at least a first and a second print head each being configured to dispense one or more coating substances onto the at least one thread when activated; and a control unit configured to determine if a maintenance sequence is to be performed on at least the first print head, and if so schedule said maintenance sequence on at least the first print head. A method is further provided.

An aim is to provide a technique for obtaining a higher quality print image by reducing a banding caused upon printing using a printing head having nozzle rows. As a solution, an activated nozzle row is reselected each time when the activated nozzle row has discharged ink for a preset number of times, and in each scan, an interval by which the activated nozzle row discharges ink in a main scanning direction is set to be an integer multiple of a resolution of an image to be printed on a print medium in the main scanning direction.

An inkjet printing and an inkjet printing method are provided. The inkjet printing device includes a stage comprising a substrate mounting part configured to receive a target substrate mounted thereon, a print head unit located above the stage and configured to spray an ink including a plurality of particles, and a suction device located at a side of the substrate mounting part and configured to generate negative pressure thereon.

A recording apparatus includes a carriage which includes a recording head that performs recording on a medium and is movable in a predetermined direction; and a power supply unit that supplies power for driving drive targets including the carriage, wherein the power supply unit is located at a position in a movement area of the carriage. The power supply unit is disposed on an apparatus front side with respect to the movement area of the carriage in an apparatus depth direction, which is a direction intersecting the movement direction of the carriage. The power supply unit is disposed on an upper side of a medium transportation path in the vertical direction.
