A new mechanism of paper-separation system is proposed to realize a highly reliable paper handling system for printers. The system consists of a pair of parallel electrodes and paper pile between the electrodes. In this system, electrostatic separation of a piece of paper was realized always at the top of the pile when the applied voltage exceeded a threshold voltage to generate electrostatic force larger than the weight of a piece of paper. The threshold voltage was about some kV, and it agreed with the numerical value calculated by the finite element method for the electrostatic field. Additionally, lateral pull-off force of a paper from the attached electrode was measured to confirm the required force to feed the separated paper. The value was in the order of 10 μN/(mm)^2 that was also in the same order as the calculated pull-off force estimated from the electrostatic force between the plate electrode and the adhered paper and the friction coefficient between them.
