A controller of an inkjet printing apparatus is configured to receive first data, which an information processing apparatus transmits in response to receipt of a print instruction. The first data includes an instruction to move the cap from a covering position to a spaced position. Upon receipt of the first data, the controller determines a location of the cap. Then, upon determination that the cap is located at the spaced position, the controller determines the state of the driving force transmission assembly. The controller switches the state to the first state by moving the carriage to the non-recordation area in response to determination that the state is not the first state. Then, the controller receives second data, which includes image recordation condition, from the information processing apparatus, in response to determination that the state is the first state or after switching of the state to the first state is started.

In one example, a datuming system to position a printhead assembly relative to a component external to the printhead assembly includes a first datum on the printhead assembly to establish a first plane, a first line, and a first point and a second datum on the printhead assembly to establish a second plane orthogonal to the first plane, a second line, and a second point.

A liquid ejecting apparatus includes: an apparatus main body; a plurality of liquid ejecting heads that have a nozzle-formed surface; a unit base to which the plurality of liquid ejecting heads are fixed; and a lifting-lowering mechanism that is fixed to the apparatus main body and causes a position of the nozzle-formed surface to be shifted with respect to the apparatus main body. The lifting-lowering mechanisms are disposed in a direction orthogonal to a direction in which the plurality of liquid ejecting heads are aligned, in an in-plane direction of the nozzle-formed surface.

A mounting apparatus for mounting a printing apparatus to a structure includes an attachment part, which is attachable to the structure, and a support member upon which a printing apparatus is supportable. The support member enables the printing apparatus to be located in a desired position along a first axis, which extends in a first direction relative to the structure, and wherein at least a part of a footprint of the support member defined in a first plane, which is substantially transverse to the first axis, overlaps at least a part of a footprint of the printing apparatus defined in a second plane, which is substantially transverse to the first axis.

A head attachment/detachment jig that is used for attachment/detachment of a head which ejects ink droplets and is fixed on a base member by a fastener member when replacing the head, the head attachment/detachment jig, includes a frame member that is attachable to and detachable from the head; and a tip tool that has a tip part and a top part, and is held to be turnable and movable forward and backward with respect to the frame member, wherein the tip part of the tip tool has a shape that is capable of turning the fastener member, and the top part of the tool has a shape that is formed to be capable of turning the tip tool by a different tool from the tip tool.

The invention relates to a device for printing on edge bands including at least one printhead for producing a printed image on the edge band; a linear drive for moving the at least one printhead in a printing direction within a printing region between two end positions; a feeding apparatus for feeding the edge band into the printing region in a transport direction; and a control apparatus for controlling the at least one printhead, the linear drive and the feeding apparatus. The technical problem of technically and economically improving the process of printing on edge bands is solved in that the transport direction of the edge band is oriented substantially parallel to the printing direction. The invention further relates to a method for printing on edge bands.

A printhead die assembly includes first and second printhead die. Each of the first and second die has a respective first surface including ink dispensing devices constructed thereon, and a respective second surface opposite the first surface. Each of the first and second die includes nozzles for the ink dispensing devices. The first and second die are positioned so that the second surface of the first die faces the second surface of the second die, and the nozzles of the first die are aligned with the nozzles of the second die.

A controller determines the amount of driving by a sub-scanning driver and the number of nozzles to be used in accordance with a maximum amplitude of vibration of an inkjet head in a sub-scanning direction, where the maximum amplitude is detected by a displacement detecting sensor when the inkjet head is moved in the sub-scanning direction before starting printing. Then, while moving the inkjet head in a main-scanning direction, the controller performs printing by selecting nozzles to be used in accordance with displacement of the inkjet head in the sub-scanning direction detected by the displacement detecting sensor.

A liquid ejection apparatus is provided that includes a plurality of liquid ejection head units that are configured to eject liquid onto a conveyed object being conveyed; a detection unit that is provided with respect to each liquid ejection head unit of the plurality of liquid ejection head units and is configured to output a detection result indicating at least one of a position, a moving speed, and an amount of movement of the conveyed object with respect to a conveying direction of the conveyed object; and a control unit configured to control the each liquid ejection head unit of the plurality of liquid ejection head units to eject liquid at a timing based on a plurality of the detection results of a plurality of the detection units.

A conveyed object detection apparatus includes an optical sensor configured to receive light reflected by a conveyed object; a detection unit configured to use the optical sensor to acquire a detection result indicating a position, a moving speed, or a moved amount of the conveyed object in at least one of a conveyance direction in which the conveyed object is conveyed and a direction perpendicular to the conveyance direction, or a combination of the position, the moving speed, and the moved amount; and a setting unit configured to set an aperture value and an exposure time concerning the optical sensor based on the detection result.
