Inkjet printer

An inkjet printer comprising:

• a conveyer configured to convey a sheet along a conveyance direction;
• a recording head configured to discharge ink toward the sheet being conveyed by the conveyer;
• a carriage mounting the recording head thereon and being configured to move along a scanning direction;
• a corrugation mechanism configured to shape into a corrugated shape, in which an amount of a gap between the recording head and the sheet is increased and decreased alternately along the scanning direction, at a corrugating position;
• and
• a controller configured to execute an operation comprising:
• a conveying step, in which the sheet is conveyed by the conveyer;
• and
• a recording step, in which the carriage is moved in the scanning direction and the recording head is manipulated to discharge the ink toward the sheet,
• wherein the recording step comprises:
• a first discharging step, in which, after the conveying step and on condition that the sheet is present at the corrugating position, the recording head is manipulated to discharge the ink toward a targeted position on the sheet along the scanning direction at a first discharging timing;
• and
• a second discharging step, in which, after the conveying step and on condition that the sheet is absent at the corrugating position, the recording head is manipulated to discharge the ink toward the targeted position on the sheet along the scanning direction at a second discharging timing which is deviated from the first discharging timing, the farther the targeted position being separated from a reference position on the sheet along the scanning direction, the more largely the second discharging timing being deviated from the first discharging timing.
