Impact energy is an important parameter in impact printing. Increasing demands on speed, print quality, noise levels, etc., make it more and more important to control that energy. Present technology generally uses an open-4oopsystem with a hammer solenoid driver so that the actual energy is poorly controlled because of the build-upof tolerances.
