  • Patent number: 11279153
    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.
