ABSTRACT:
An ink jet printer includes a charge decoupling device which permits fluid flow of electrically conductive fluid between a high voltage electrode and a grounded fluid reservoir while presenting a high impedance electrical path therebetween. The charge decoupling arrangement includes a nonconductive casing defining an interior casing cavity which is separated into an upper and a lower portion by means of a perforated plate extending horizontally across the cavity. A plurality of drop stabilizers are mounted adjacent associated ones of the perforations to define downwardly extending capillary fluid paths from the perforations into the lower portion of the cavity to form fluid drops which drip off of the bottoms of the stabilizers. The break up of the fluid into drops provides the high impedance path through the charge decoupling device, thus ensuring that the deflection electrode arrangement and the catchers are substantially electrically isolated.
