■ Separation
This control separates paper from the ITB by elastic force of the paper (curvature separation method).
In the case of thin paper which has low elastic force, the Static Eliminator removes positive potential at the back of the paper.
This reduces electrostatic absorption force of the paper so that paper can be easily separated.
