A carriage includes: a base plate; a liquid jet head including a support plate attached to the base plate; a first engagement portion formed on one end in a Y direction of the support plate; a fixing tool for positioning and fixing the support plate with respect to the base plate, the fixing tool being fixed to the base plate slidably in an X direction by screws and engaged with the first engagement portion; and a flat spring portion that presses the fixing tool toward the base plate. The fixing tool allows movement in the Y direction of the first engagement portion with respect to the fixing tool, and restricts movement in the X direction of the first engagement portion and movement in a thickness direction of the base plate of the first engagement portion with respect to the fixing tool.

Provided are a carriage structure capable of preventing a carriage from contacting a side edge of a print medium, without requiring a discharge roller and facilitating reducing device size, and a printer having the carriage structure. Disposed to a carriage 21 carrying and inkjet head 22 and moving bidirectionally through a range of movement including the conveyance path of a cut-sheet paper S are: a panel member 78 able to protrude in the direction of carriage 21 movement; and a moving mechanism 126 causing the panel member 78 to protrude to the conveyance path of the cut-sheet paper S when the carriage 21 is at a standby position (home position) set in the range of carriage 21 movement.

A printing system includes a first member and a second member. The second member is positioned parallel to the first member. The system further includes a first extensible member and a second extensible member. The system further includes a first gripper and a second gripper. One end of the first extensible member is mounted to the first member and the other end of the first extensible member is mounted to the first gripper. One end of the second extensible member is mounted to the second member and the other end is mounted to the second gripper. A controller operates a first actuator operatively connected to the first and second extensible members.

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 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.

There is provided a printer including: a conveyance unit; a liquid jetting head including at least one nozzle array in which nozzles are arrayed; a carriage; a guide; a carriage moving unit; a memory; and a controller. The controller performs printing by performing scan printing operation and a conveyance operation multiple times repeatedly and adjusts jetting timings of the liquid jetted from the nozzles at positions in a scanning direction based on pieces of inclination information corresponding to the respective positions. In second or subsequent scan printing operation of the multiple times of scan printing operation, the controller delays or advances, based on the inclination information, the jetting timing in the second or subsequent scan printing operation relative to the jetting timing in scan printing operation immediately before the second or subsequent scan printing operation more greatly, as inclination of the at least one nozzle array increases.

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.
