The Intelli-Zone Cut 680AD is designed to bring you affordability along with the convenience of electric paper cutting. The 680AD features a fully electric powered cutting knife, backstop and clamp. The press of a few buttons activates the clamp and blade. The backstop moves back and forth by turning a knob located on the front of the machine. A digital display alerts the operator exactly where the backstop is in either millimeters or inches and an optical cutting knife shows the operator exactly where the blade will cut.
