ABSTRACT:
An ink jet printer which does not utilize high voltage potentials to deflect non-printing ink particles. Nozzles are arranged in two parallel lines to jet ink particles. These ink particles pass between first and second parallel electrodes disposed between the nozzles and a recording medium. The non-printing ink particles from both lines of nozzles are charged with the same polarity. The repulsive force between the two lines of particles and the induced charges in the electrodes force the non-printing ink particles towards the electrodes. In one embodiment, the electrodes are solid plates and a gutter is provided between ends of the plates and the recording medium to recover ink particles, while in a second embodiment, the electrodes are metal meshes and a suction device is provided behind the meshes to collect the non-printing ink particles.
