Abstract: A controller determines whether, in a case where feeding of a subsequent sheet is performed in a first feed condition, a subsequent sheet contacts conveyance rollers during recording on a preceding sheet, the first feed condition being that feeding of the subsequent sheet is started at a first timing before recording on the preceding sheet ends and that the subsequent sheet is fed at a first velocity, and in response to determining that the subsequent sheet contacts the conveyance rollers during recording on the preceding sheet, controls the feed roller to perform feeding of the subsequent sheet in a second feed condition or a third feed condition, the second feed condition being that the feeding of the subsequent sheet is started at a second timing later than the first timing, the third feed condition being that the subsequent sheet is fed at a second velocity lower than the first velocity.

Abstract: When an image recording apparatus records an specific image over a boundary between a first dot formation range where dots are to be formed in a preceding recording operation of two consecutive recording operations and a second dot formation range where dots are to be formed in a subsequent recording operation of the two consecutive recording operations, the apparatus sets, as a correction portion, an end portion in a scanning direction of a specific region including at least one of a first boundary region adjacent to the second dot formation range and a second boundary region adjacent to the first dot formation range in the specific image, and forms the dot placed at the correction portion by discharging liquid of a discharge amount smaller than the discharge amount set for a dot element corresponding to the dot from nozzles.

Abstract: An image recording apparatus includes a roller pair for transporting a sheet, a recording head, and a controller. The controller determines a linefeed amount by which the sheet is transported by the roller pair between corresponding two adjacent passes of the recording head. The controller executes image recording on the sheet by alternately repeating a linefeed operation for rotating the roller pair by the determined linefeed amount to transport the sheet in a transport direction, and a pass recording operation in which the controller causes the roller pair to stop and the recording head to perform a pass and to record part of an image on the sheet. Upon determining that a linefeed operation would cause the sheet to travel past the roller pair while the roller pair is decelerating, replace for the linefeed operation a determined linefeed amount by an adjusted linefeed amount.

Abstract: An image recording apparatus includes a housing, an operation panel, a sheet conveyor, a recording device, and a cutting device. The operation panel is disposed at a first-side face of the housing in a first direction. The first direction is orthogonal to a vertical direction and extends from a first side to a second side of the image recording apparatus. In the first direction, the cutting device is closer to the first side of the image recording apparatus than the recording device is and closer to the second side of the image recording apparatus than the operation panel is. The cutting device includes a cutter, and a cutter carriage to move with the cutter mounted thereon along a second direction orthogonal to the first direction and the vertical direction. The operation panel overlaps a movable area of the cutter carriage when viewed in the first direction.

Abstract: An image recording apparatus includes a recording unit, first and second rollers, a guide member, and a cutting unit. The recording unit performs image recording on a sheet conveyed in a conveying direction on a first conveyance path. The first roller is located further downstream than the recording unit in the first conveyance path. The second roller is located further downstream than the first roller in the first conveyance path. The guide member has a guide surface that forms a second conveyance path extending from a connection position of the first conveyance path between the first roller and the second roller. The cutting unit is located between the connection position and the second roller, cuts a sheet, and has a cutter. The guide member changes in posture between a first posture for forming the second conveyance path and a second posture for opening the second conveyance path.

Abstract: An image recording apparatus is configured to perform a conveying process of a recording medium using a conveying roller and a discharging roller, a recoding process of recording an image on the printing sheet when the conveying process is not performed, and an adjusting process. In the adjusting process, among a plurality of conveying processes performed within a period from the start of the conveying process for an n-th printing sheet until the timing which is after the start of the conveying process for an (n+1)-th printing sheet, the conveying amount of the printing sheet subject to at least one conveying process is adjusted such that a timing when the trailing end of the n-th printing sheet passes through the discharging roller is within one of the acceleration period and the deceleration period of the conveying process for the printing sheet.
