Patent ID: 7896459

Claim:
An image recording device comprising: a recording unit configured to eject ink onto a sheet of recording medium; a platen disposed opposite to the recording unit and configured to support the sheet; a pair of upstream rollers disposed upstream of the recording unit and the platen in a sheet conveying direction and configured to convey the sheet in the sheet conveying direction when rotating in a forward direction; and a controller, wherein when the sheet is supported on the platen and pinched between the pair of upstream rollers, the controller is configured to control the recording unit to eject the ink onto a particular portion of the sheet, wherein the controller is further configured to determine whether a predetermined condition relating to ink ejection from the recording unit is satisfied by the ink ejection onto the particular portion, wherein when the controller determines that the predetermined condition is satisfied by the ink ejection onto the particular portion, the controller is configured to rotate the pair of upstream rollers in a reverse direction opposite the forward direction to convey the sheet in a direction opposite the sheet conveying direction, and is configured to subsequently stop rotating the pair of upstream rollers in the reverse direction, such that the pair of upstream rollers pinch the sheet for a particular amount of time, and wherein the upstream rollers are configured to hold the sheet in a predetermined shape for the particular amount of time to correct a deformation formed in the particular portion of the sheet by the ink ejected onto the particular portion of the sheet, and wherein when the controller determines that the predetermined condition is not satisfied by the ink ejection onto the particular portion, the controller is configured to rotate the pair of upstream rollers in the forward direction to convey the sheet in the sheet conveying direction, and is configured to cause the recording unit to eject ink onto a further portion of the sheet adjacent to the particular portion of the sheet.
