A recording device includes a medium support portion, a recording head configured to eject a liquid toward a medium supported by the medium support portion, a gantry that includes the recording head and is configured to move relative to the medium support portion in a Y-axis direction, a first linear scale attached to a first attachment member, a first encoder configured to read markings of the first linear scale while moving, together with the gantry, relative to the medium support portion in the Y-axis direction to detect a displacement of the gantry, and a length adjustment unit configured to adjust a length of the first linear scale attached to the first attachment member, by adjusting a tension in the Y-axis direction applied to the first linear scale.

A control device includes a processor and a memory storing computer-readable instructions that, when executed, cause the processor to control a print execution device to perform printing on a first sheet and a second sheet, when at least one specific condition is not satisfied with respect to the first sheet being printed, after final partial printing on the first sheet, start final conveyance of the first sheet in a state where a plurality of nozzles are located within a sheet range in which the first sheet is placed in a main scanning direction, and when the at least one specific condition is satisfied, after the final partial printing on the first sheet, move a print head to such a position that the plurality of nozzles are located outside the sheet range in the main scanning direction, before starting the final conveyance of the first sheet.

A method for printing on the surface of an object uses a print head generating ink drops to print at least a first swath and subsequently a second swath of ink onto the surface in such a way that the swaths are mutually adjacent and overlap in a strip. The first and second swaths are printed as solid areas and the swaths are XY stitched in the strip. In the strip, at least one of the two swaths is additionally stitched by using a function of an ink amount profile in a Y direction. High-quality or even highest-quality printed products can therefore be produced, in particular avoiding defects that are visible to the human eye in a region of overlap or a strip between swaths that are printed next to one another.

The present teachings disclose various embodiments of a printing system for printing substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a Y-axis motion system and a Z-axis moving plate that are configured to substantially decrease excess thermal load within the enclosure by, for example, eliminating or substantially minimizing the use of conventional electric motors.

Described is an assembly of a guiding structure and a print head carriage, the print head carriage comprising a base carriage controllably movable relative to the guiding structure along a first horizontal axis, the print head carriage comprising a sub-carriage controllably movable relative to the base carriage along a second horizontal axis. The print head carriage comprises an intermediate carriage controllably movable relative to the base carriage along a vertical axis, the sub-carriage mounted on the intermediate carriage for moving together with the intermediate carriage relative to the base carriage, the sub-carriage controllably movable relative to the intermediate carriage along the second horizontal axis.

An imaging apparatus includes a print engine having a printhead that generates ink drops, and a printhead carrier that carries the printhead in a first direction and in a second direction opposite the first direction. A controller determines an initial print direction based on ink drop information obtained by printing patches in the first direction and in the second direction, wherein the ink drop information includes a respective chromatic value of each of the patches. The controller is operatively coupled to the print engine to print an image based on the initial print direction.

A control device includes a processor and a memory storing computer-readable instructions that, when executed, cause the processor to control a print execution device to perform printing on a first sheet and a second sheet, when at least one specific condition is not satisfied with respect to the first sheet being printed, after final partial printing on the first sheet, start final conveyance of the first sheet in a state where a plurality of nozzles are located within a sheet range in which the first sheet is placed in a main scanning direction, and when the at least one specific condition is satisfied, after the final partial printing on the first sheet, move a print head to such a position that the plurality of nozzles are located outside the sheet range in the main scanning direction, before starting the final conveyance of the first sheet.

A recording device includes a medium support portion, a recording head configured to eject a liquid toward a medium supported by the medium support portion, a gantry that includes the recording head and is configured to move relative to the medium support portion in a Y-axis direction, a first linear scale attached to a first attachment member, a first encoder configured to read markings of the first linear scale while moving, together with the gantry, relative to the medium support portion in the Y-axis direction to detect a displacement of the gantry, and a length adjustment unit configured to adjust a length of the first linear scale attached to the first attachment member, by adjusting a tension in the Y-axis direction applied to the first linear scale.

A liquid ejecting apparatus includes a head that can eject liquid, a carriage that holds the head and can move in an intersecting direction, a support portion that can support a medium from a side opposite the side on which the head is located, a frame portion that is provided upstream of the carriage in the transport direction, the carriage being attached to the frame portion, a cover portion that covers the carriage, a first adjustment part that is attached to the frame portion, and a second adjustment part that is attached to a positioning portion. A difference between a first adjustment distance and a second adjustment distance is smaller than a difference between a first distance and a second distance.
