Abstract: A liquid ejecting head includes head units each of which includes a corresponding head substrate and ejects liquid, flexible cables each of which has one end connected to the corresponding head substrate, and a common member including the head units that are fixed thereto. In the liquid ejecting head, when a first direction, a second direction, and a third direction are directions that orthogonally intersect each other and the common member is placed on a virtual surface defined by the first direction and the second direction and has a thickness extending in the third direction, the common member extends more in the first direction than in the second direction. In addition, a fixation region in which each of the flexible cables and the corresponding head substrate are fixed to each other extends more in the second direction than in the first direction when viewed in the third direction.

Abstract: A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a −Z side of the first cover, has the rotation shaft along a Y-axis on the Z− side, and is rotatable with respect to the apparatus main body.

Abstract: A controller can acquire, as information of a recording device, first information that can determine that a recording type of the recording device is an ink-jet type, and second information that can determine the recording type of the recording device is a laser type. The controller acquires the information of the recording device, performs the post-processing based on a first setting when the information of the recording device includes the first information capable of determining that the recording type is the ink-jet type, and performs the control of the post-processing based on a second setting different from the first setting when the information of the recording device includes the second information capable of determining that the recording type is the laser type.

Abstract: A recording system includes a transportation unit that transports a paper sheet, an ejection unit that ejects an ink, a heating unit that heats the paper sheet, a discharge unit to which the paper sheet is discharged, and a control unit. The control unit specifies an amount of ejection of the ink from the ejection unit. The control unit also controls an operation of the heating unit such that an undried region where the ink on the paper sheet is not dried and a dried region where the ink on the paper sheet is dried are formed on the paper sheet. Then, the control unit controls a transporting operation by the transportation unit such that the paper sheet on which the dried region and the undried region are formed is discharged to the discharge unit.

Abstract: A liquid ejecting apparatus includes a liquid path comprising a filter and a liquid storing chamber for supplying liquid to a liquid ejecting head. The liquid storing chamber has an inlet, a bubble retention space disposed above the inlet, a bottom disposed below the bubble retention space, and a first outlet and a second outlet. (i) The first outlet is located on one side of an imaginary center line passing through the center of a projected area, and the second outlet is located on the other side of the imaginary center line. Alternatively, (ii) the first outlet and the second outlet are located outside a projected area defined by projecting the bubble retention space onto the bottom.
