A method for deskewing a sheet. The method includes positioning a lower roller pair and at least one upper roller pair to form a substantially vertical transport path, wherein the lower roller pair and at least one upper roller pair each form a nip. The method includes driving the lower roller pair and the at least one upper roller pair so as to transport the sheet upward along the substantially vertical transport path, opening the nip formed by the at least one upper roller pair as a trailing edge of the sheet approaches the lower roller pair. The method further includes continuing to drive the lower roller pair so that the trailing edge passes through the nip formed by the lower roller pair and upward movement of the sheet ceases with the trailing edge supported by the lower roller pair, wherein gravity and continued rotation of the lower roller pair work together align the trailing edge with the lower roller pair.
