Media Separation with Electrostatic Force

      For media separation, such as papers in printer stacks,
electrostatic force may be used.

      An electrostatic roller 1 take up the paper from a stack 5.
After that, the paper will be moved forward to the transport rollers
3, at this time the paper will be electrostatic discharged by ground
brushes 2.  The paper stack will always be held in the same distance
to the electrostatic rollers with springs 4.  To avoid multiple
sheets taken from the paper stack by electrostatic roller, the
bracket 6 is used, as it is used in numbers of paper stack systems.

      Main advantage, no ware off of roller, no noise, and very small
and light forms picked off, what is impossible with friction roller
systems.
