Abstract
A drop deflection device suitable for use in a drop marking system employs an electret. Electrically conductive marking drops such as inks are given an electrical charge. The drops pass between a pair of deflections plates at least one of which is formed by an electret (a dielectric material which has been subjected to corona discharge to create a relatively permanent electrically charged material body). Depending upon the presence or absence of a charge on a particular drop, it will be deflected by the field between the plates on to a substrate for marking. If uncharged, the drops continue to a collection device which returns them to the ink reservoir.
