Abstract
A method for folding sheets of a medium is provided. The method includes rotating a cam mechanism through a first period of rotation to cause a crease blade to move in a contact direction to create a crease in the sheets by pushing the sheets between a pair of first rolls, and rotating the cam mechanism through a second period of rotation to cause the crease blade to move in a retracting direction away from the sheets and cause a lever to move first and second scissor arms such that the pair of first rolls is separated and a pair of second rolls is separated. One of the second rolls is movable by the second scissor arm.
