An image recording apparatus having a recorder, a first driving device, a second driving device, a driving-force transmission device, a sensor, a memory, and a controller to conduct a conveying process and a recording process alternately and repetitively, is provided. In the conveying process, on condition that a rotationally driven amount of the first driving device exceeded a target rotation amount, the controller conducts feedback control on the first driving device to rotate reversely. On condition that the first driving device was rotationally driven reversely under the feedback control, the controller stores a maximum value and a stopping value in the memory, determines a correction value, and determines a post-correction rotation amount based on the target rotation amount and an amount corresponding to the correction value, and in the conveying process, the controller drives the first driving device rotationally by the post-correction rotation amount.

A printer is provided with a head, a platen, a conveyer, and a processor. The head performs printing on a print medium. The platen supports the print medium. The conveyer conveys the platen in a conveyance direction. The processor acquires a platen size. The platen size is a size of the platen in the conveyance direction. When the processor acquires a first platen size, the processor controls a conveyance operation of the platen such that a conveyance time period of the platen between a set position and a printing position is a first time period. When the processor acquires a second platen size, the processor controls the conveyance operation of the platen such that the conveyance time period of the platen between the set position and the printing position is a second time period different from the first time period.
