Abstract: A printer includes a container configured to store recording agent, a print head configured to eject the recording agent, and a controller configured to permit the printer to perform printing until a print permission amount, different from a remaining amount of the recording agent in the container, reaches a first threshold. The print permission amount is information regarding a quantity, of the recording agent or sheets usable by the printer. The controller is further configured to receive an instruction to perform user cleaning to clean the print head by ejecting the recording agent from the print head, and in response to the receipt of the instruction to perform the user cleaning, cause the printer to perform the user cleaning when the print permission amount has not reached a second threshold, whereas restricting execution of the user cleaning when the print permission amount has reached the second threshold.

Abstract: A recording device performs an initial introduction process of executing initial introduction to enable a recording operation by a recording unit in an initial state where a recording operation by a recording unit is not enabled, a completion determining process of determining whether the initial introduction is normally completed, and a shifting process of shifting a state of the recording device from the initial state to a state where the recording operation by the recording unit is enabled within a permitted recording number of the recording operation by the recording unit in response to determining that the initial introduction is normally completed in the completion determining process.

Abstract: An image recording apparatus includes a conveyance mechanism conveying a sheet-shaped medium in a conveyance direction, a recorder recording an image on the conveyed sheet-shaped medium, and a controller. The conveyance mechanism selectively conveys a first sheet-shaped medium accommodated in a first accommodation part, and a second sheet-shaped medium accommodated in a second accommodation part and longer than the first sheet-shaped medium in the conveyance direction. The controller causes, based on a recording command, the conveyance mechanism to convey a sheet-shaped medium from one of the first and second accommodation parts, and causes the recorder to record an image on the sheet-shaped medium.

Abstract: An image recording apparatus includes a controller to calculate n that is a maximum natural number satisfying nX?X0, where X0 represents a width of a sheet medium, and X represents a longest one of respective lengths, in a width direction of the sheet medium, of a plurality of first images or a single second image based on image data. The plurality of first images are arranged along a longitudinal direction of the sheet medium. When the calculated n is equal to or more than two, the controller performs a juxtaposed image recording process to control a print engine in such a manner that two or more and n or less images, among the plurality of first images or among a plurality of divisional images into which the single second image is divided, are recorded to be arranged side by side along the width direction.

Abstract: An image forming apparatus includes a controller that performs one or more times a first image forming process including performing image formation on a sheet medium, and conveying the sheet medium in a conveyance direction by rotating a first roller by a first number of rotations and rotating a second roller disposed downstream of the first roller in the conveyance direction by a second number of rotations smaller than the first number of rotations. When a count of times the first image forming process has been performed becomes a particular number of times, the controller performs a second image forming process including performing image formation on the sheet medium, and conveying the sheet medium by rotating the first roller by a third number of rotations smaller than the first number of rotations and rotating the second roller by the second number of rotations.

Abstract: A liquid ejection apparatus includes a medium container, a liquid ejection head, a mover, and a controller. The mover is configured to execute, among a first moving operation of moving a sheet-like medium and a second moving operation of moving the liquid ejection head, at least the first moving operation. The controller causes the liquid ejection head and the mover to alternately or simultaneously perform execution of the first moving operation and execution of ejection and second moving operations, and adjusts at least one selected from the group of an amount of liquid to be ejected, a time interval between the ejection operations when alternately performing execution of the first moving operation and execution of the ejection and second moving operations, and a moving speed of the medium when simultaneously executing the ejection operation and the first moving operation, according to medium information relating to curling of the medium.

Abstract: An image forming apparatus includes: a signal output unit configured to output a signal in response to a user operation; a reading unit configured to read a document and generate image data having a first resolution or a second resolution lower than the first resolution; a recording unit configured to form an image on a recording medium; and a controller configured to control the reading unit and the recording unit and execute: (a) primary preparation operation start processing of, when a signal is output, controlling the reading unit so as to start a first preparation operation or a second preparation operation; (b) determination processing of determining; (c) secondary preparation operation start processing and/or reading processing; (d) decision processing of deciding the continuous number of recording copies; and (e) recording processing of causing the recording unit to form the image on the recording medium.

Abstract: A printing device includes: a supply tray; a sensor; a print unit; a memory; and a controller. The sensor is configured to selectively output a first signal indicating absence of a sheet on the supply tray and a second signal indicating presence of a sheet on the supply tray. The controller is configured to: create first authentication information when the first signal changes to the second signal; store the first authentication information in the memory; accept a job that uses a sheet on the supply tray; determine that a first job is accepted, the first job being such a job that accompanies second authentication information, the first job being executable when the second authentication information is in coincidence with the first authentication information; and control the print unit to execute the first job.

Abstract: The presence or absence of outside light is individually decided with respect to each of the time of executing AFE adjusted value acquiring processing, the time of executing LED adjusted value acquiring processing and the time of executing black correction data acquiring processing. In the case of deciding that the outside light is present, a parameter in the case of deciding that the outside light is present is modified to a predetermined value or a reacquired value. As a result of this, even when an incident state of outside light changes at the time of acquiring each of the parameters, it can properly be switched whether or not their parameters are replaced with the predetermined value or the reacquired value.
