● Separation
Purpose
This control separates paper from the ITB by elastic force of the paper. (Curvature separation method)
Description of Control (in case of thin paper)
Since the elastic force of thin paper is weak, paper cannot be separated only by the elastic force of the paper.
In order to solve this problem, positive charge on the back side of paper is removed by the Static Eliminator to weaken the
electrostatic absorption force of the paper.
