Abstract: Provided are a medium conveying device and an inkjet printer that can convey a medium stably. In a case where a paper P is conveyed along a plane in a conveying unit 40, a posture of the paper P is corrected by a posture correction unit 20, and then the paper P is delivered to the conveying unit 40 by a delivery unit 30. The delivery unit 30 holds a leading end portion of the paper P of which the posture is corrected by the posture correction unit 2 with a paper holding bar 31, and delivers the paper P to the conveying unit 40 by moving the paper holding bar 31 linearly along a conveying direction of the paper P by the conveying unit 40.

Abstract: When a liquid ejection head and a first wiping unit are moved relatively to clean a surface, the first wiping unit making a first wiping member travel in a first direction, a direction opposite to the first direction is used as a moving direction of the head with reference to the first wiping member in relative moving therebetween. When the head and a second wiping unit are moved relatively to each other to clean the surface, the second wiping unit making a second wiping member travel in a second direction having a component of a direction opposite to the first direction, a direction opposite to the second direction is used as a moving direction of the head with reference to the second wiping member in relative moving therebetween to move the second wiping unit and the head relatively to clean the same area on the surface.

Abstract: In an image recording device, in a case where a J-th nozzle (H2 [3]) of a certain image recording head (H2) among plural image recording heads (H1, H2) is in a discharge defect state, a dot size of an image recording droplet discharged from a J-th nozzle (H1 [3]) of an image recording head (H1) other than the image recording head (H2) is changed to a size within dot sizes used in normal image recording in a high-speed image recording mode, which is larger than a dot size of an image recording droplet to be discharged from the discharging nozzle (H2 [3]). In a low-speed image recording mode, the dot size of the image recording droplet discharged from the discharging nozzle (H1 [3]) is changed to a size which is larger than the largest dot size among dot sizes used in the normal image recording.

Abstract: Provided is a printer capable of efficiently printing an image on a cylindrical recording medium with simple control.
A plurality of printing start positions are set on an outer circumferential surface of a recording medium. A processor performs transport control of the recording medium for a transport unit and printing control of the recording medium for a printing unit provided in each station. In the transport control, control for the transport unit is performed such that the recording medium is rotated at a constant speed, movement of the recording medium is stopped each time the recording medium arrives at the station, and the movement of the recording medium is restarted after printing at the station is completed. In the printing control, control for the printing unit of each station is performed such that image printing is started from the printing start position that first reaches the printing position.
