An inkjet printer having a conveyer, a recording head, a carriage, a corrugation mechanism, and a controller is provided. The controller executes an operation including a conveying step to convey a sheet and a recording step to discharge ink through the recording head toward the sheet. The recording step includes a discharging step, in which the recording head is manipulated to discharge the ink toward the sheet in response to the carriage being placed in a discharging position when the sheet is in a nipped condition, in which the sheet is nipped by the conveyer roller unit; and a corrected discharging step, in which the recording head is manipulated to discharge the ink toward the sheet in response to the carriage being placed in a corrected discharging position, when the sheet is in a non-nipped condition, in which the sheet is not nipped by the conveyer roller unit.
