The drive mechanism comprises a motor having a rotating axis and an intermediate element attached to the rotating axis, being the intermediate element to contact the carriage guide as to move the carriage along the carriage guide.

It is disclosed a carriage, e.g., for a printing system comprising a housing being the carriage to move relative to a carriage beam along a scan direction, the carriage comprising: a drive mechanism to move the carriage; and an alignment guide; wherein the alignment guide is parallel to the carriage beam and comprises a first flat surface and a second flat surface and wherein the carriage comprises a plurality of rolling elements including a first rolling element and a second rolling element being the first rolling element to contact the first flat surface and the second rolling element to contact the second flat surface.

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.

The present disclosure provides an imaging apparatus (100) comprising a scanning printer carriage (110), a carriage motor (120), a transmission belt (130) between the carriage motor (120) and the scanning printer carriage (110), a data control unit (140) to provide print data (200) to the carriage motor (120) and the scanning printer carriage (110), and a power source (150) to provide power (300) to the carriage motor (120), and the scanning printer carriage (110). The data control unit (140) transmits print data (200) to the scanning printer carriage (110) by wireless data transfer (201), and the power source (150) transmits power (300) to the scanning printer carriage (110) through an electrically conductive element (302) in the transmission belt (130).

An inkjet printing apparatus includes a mounting unit where a recording medium is mountable, a head unit that ejects ink droplets to the recording medium, a planar direction driving unit that drives at least one of the head unit ejecting the ink droplets and the mounting unit to move in a planar direction and that changes a relative positions of the head unit and the mounting unit in the planar direction, and a height direction driving unit that changes a relative positions of the head unit and the mounting unit in a height direction perpendicular to the planar direction. The planar direction driving unit has a moving speed changing mechanism that changes a carriage speed between the head unit and the mounting unit in the planar direction. The height direction driving unit has a distance changing mechanism that changes a distance between the head unit and the mounting unit.

A liquid discharge apparatus includes: a discharge head including nozzles; a head scanning mechanism that reciprocatingly moves the discharge head in a main scanning direction; a conveyor that conveys a recording medium in a sub-scanning direction; and a controller. In one pass, the controller executes: recording processing in which an image is formed on the recording medium by moving the discharge head in the main scanning direction and discharging liquid from the discharge head; setting processing in which the discharge head moves to a starting position of the recording processing for a subsequent pass following the one pass by changing a moving direction of the discharge head at a standstill position; and conveyance processing in which the recording medium is conveyed in the sub-scanning direction.

A controller is configured to: when both a first conveyor and a second conveyor are operating concurrently, determine whether a reference current value exceeds a threshold value, the reference current value being obtained based on at least one of a first driving current that is a driving current of the first conveyor and a second driving current that is a driving current of the second conveyor; in response to determining that the reference current value exceeds the threshold value, continue an operation of an earlier-driven conveyor that is one of the first conveyor and the second conveyor that is started at earlier timing, and temporarily stop an operation of a later-driven conveyor that is one of the first conveyor and the second conveyor that is started at later timing; and after a driving current of the earlier-driven conveyor drops to a particular standard, restart the operation of the later-driven conveyor.

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 liquid ejecting apparatus includes a carriage that mounts a liquid ejecting head provided with a nozzle surface in which nozzles to eject a liquid are formed, and is configured to move the liquid ejecting head between an ejection area used to cause the liquid ejecting head to eject the liquid onto a medium and a maintenance area used to perform maintenance of the liquid ejecting head, and a liquid receiving portion that has a size equal to or larger than the nozzle surface, is opposed to the nozzle surface located at a detachment position defined in the maintenance area, and receives the liquid discharged from the nozzles when detaching a liquid supply coupling portion detachably coupled to the liquid ejecting head.
