Abstract
A first convey roller conveys a sheet in a sheet conveying direction such that a leading edge of the sheet passes through a nip of a second convey roller disposed downstream from the first convey roller. The second convey roller rotates in a reverse direction by a first rotation amount corresponding to a first linear distance to convey the sheet in a direction opposite to the sheet conveying direction, such that the leading edge of the sheet is released from the nip of the second convey roller. In response to the rotation of the second convey roller in the reverse direction, the first convey roller rotates by a second rotation amount corresponding to a second linear distance in the reverse direction to convey the sheet in the direction opposite to the sheet conveying direction, such that the leading edge of the sheet contacts the nip of the second convey roller when the first convey roller has rotated by the second rotation amount and the second convey roller has rotated by the first rotation amount.
