Separation

Paper is separated from the ITB due to paper's elastic force.
In the case of thin paper which has low elastic force, the static eliminator reduces potential on
the back surface of paper. This reduces electrostatic adsorption of paper so that thin paper is
separated from the ITB more easily.

MEMO:
On this machine, by reducing the diameter of Secondary Transfer Inner Roller, contact
surface of the paper with the ITB is reduced. This prevents the thin paper from sticking
onto the ITB.
