A printer or copier has a sheet alignment apparatus including a pair of detents, or walls, at a right angle to one another against which the sheet is moved. To move the sheet, a sheet positioning mechanism is provided which includes two paddlewheels that engage the sheet as they rotate and that are directed offset from one another. The paddlewheels may be angled to shear with one another, and the mounting on which they are supported may be pivotable to redirect the paddlewheels.
