The invention relates to a method for digitally printing a profiled strip (1) having a plurality of digital print heads (2) which are aligned with respect to contour portions (4, 5, 6) of the profiled strip (1) and are moved in this aligned reference position (a, b, c, d) relative to the profiled strip (1) along the longitudinal strips of the profiled strip determined by the contour portions (4, 5, 6) at a predetermined distance, wherein the nozzles of the print heads (2) are controlled with respect to the ink delivery as a function of a print template. In order to ensure advantageous method conditions, it is proposed that individual contour portions (4, 5, 6) are assigned reference planes (7) by an evaluation program on the basis of data reproducing the contour (3) of the profiled strip (1) in the printing area, in that the print heads (2) are aligned with respect to these reference planes (7), and in that the nozzles of the aligned print heads (2) are controlled with respect to the ink delivery with a correction value which takes into account the deviation of the respective contour portion (4, 5, 6) from the reference plane (7).

An apparatus includes a printing head (154) comprising jet nozzles (158) spaced apart from one another, where a distance from a first jet nozzle to a second jet nozzle positioned adjacent the first jet nozzle defines a jet-spacing, a printing head position control assembly includes a first actuator assembly (102) to move the printing head along the longitudinal axis and a second actuator assembly (103) to move the printing head along a latitudinal axis, and an control unit communicatively coupled to the printing head position control assembly. The control unit causes jet nozzles to dispense drops of binder (50) while the printing head traverses a first pass trajectory along the longitudinal axis in a first direction, indexes the printing head to a second pass trajectory along the latitudinal axis, and causes jet nozzles to dispense drops of binder while the printing head traverses the second pass trajectory along the longitudinal axis in a second direction.

A printing system includes a substrate support, a printhead assembly positioned facing the substrate support, and an imager. The printhead assembly includes a plurality of dispensing nozzles extending in an ejection direction towards the substrate support and a plurality of marks. The imager is movable relative to the printhead assembly and oriented in a direction opposite to the ejection direction for capturing at least one image including the plurality of marks indicating positions of the plurality of dispensing nozzles in the printhead assembly.

The disclosed embodiments relate to a wide format single pass printing apparatus. The printing apparatus can include multiple print housings configured to receive print beams with print heads configured to print onto a substrate. The print housings can be horizontally adjacent to one another relative to a horizontal plane. The print housings can also be oriented opposite to one another. The print beams can be inserted and/or removed from each print housing from opposing ends, allowing for greater ease of access to the print beams.

In an image forming apparatus, a carriage mounts a recording head for discharging droplets, and moves in a main scan direction. A guide member slidably guides the carriage. An encoder scale is arranged along the main scan direction. An encoder sensor reads the encoder scale. The carriage includes a head mounting part for mounting the recording head, and a sensor attaching part for attaching the encoder sensor. The sensor attaching part is provided so as to be extended from the head mounting part. The encoder scale is arranged at a location which the encoder sensor can read. A partition member is provided to separate the head mounting part from the sensor attaching part in the carriage. The head mounting part is arranged in a first space, and the sensor attaching part and the encoder scale are arranged in a second space separated from the first apace by the partition member.

On a carriage that is transported in a main scanning direction by a main scanning drive portion heads are disposed so as to be displaced from each other in a sub-scanning direction, and heads are disposed so as to be displaced from each other in the sub-scanning direction. Therefore, even when an ejection failure occurs in nozzles of one of the two heads and in nozzles of one of the two heads ink can be ejected from the other head that ejects the same type of ink in main scanning. Thus, even when the ejection failure occurs in the nozzles, a deterioration in print quality can be suppressed.

An image recording apparatus, having a power source, a drivable device, a head, a motor, a carriage, a sensor, and a controller, is provided. In a recording process, the controller sets a limitation current calculated by subtracting a variable first driving current from an allowable current to the power source, controls the power source to supply the first driving current to the drivable device and simultaneously supply a variable second driving current not exceeding the maximum current to the motor, and when the controller determines, based on a signal output from the sensor, that a behavior of the carriage satisfies an error condition, on condition that the drivable device has completed a targeted conveying action, issue an error alert, and on condition that the drivable device has not completed the targeted conveying action, control the motor to cause the carriage to continue moving without issuing the error alert.

A contact member for a slidable carriage comprises a pair of roller bearings mounted at a contact side of the contact member and oriented to roll along a sliding direction of the contact member, and a pivot support surface to engage a counter surface structure of the slidable carriage.

A printer is provided with a front linear guide rail, a front linear guide block, a rear linear guide rail, a rear linear guide block, and a carriage. The front linear guide rail extends in a first direction. The front linear guide block is configured to move along the front linear guide rail. The rear linear guide rail is provided in a second direction with respect to the front linear guide rail, and extends in the first direction. The rear linear guide block is configured to move along the rear linear guide rail. The carriage is fixed to the front linear guide block and the rear linear guide block. One of the front linear guide block and the rear linear guide block positions the carriage in the second direction, and the other positions the carriage in a third direction.

A recording method according to the present disclosure is a recording method that performs recording on a recording medium, the recording method including a white ink adhesion step of adhering a white ink composition containing a white color material to the recording medium and a non-white ink adhesion step of adhering a non-white ink composition containing a non-white color material to the recording medium, in which the white ink adhesion step and the non-white ink adhesion step are performed by relative scanning between a recording head and the recording medium, the white ink adhesion step and the non-white ink adhesion step are performed by the same relative scanning on the same scanning region of the recording medium, and in the recording region to which the white ink composition and the non-white ink composition are adhered, an adhesion amount of the white ink composition is 60% by mass or less with respect to 100% by mass of an adhesion amount of the non-white ink composition per unit region.
