ABSTRACT:
In an ink jet printing system wherein a drop generator emits ink droplets for printing on a recording media, deleterious ink mist or ink dust formed as a result of ink droplets impacting on the media is collected by a collecting container disposed relative to the zone whereat ink droplets contact the media. A vacuum system is coupled to the container and extracts ink mist which is returned to the ink supply system for reuse. Airborne contamination, to components such as the drop generator, charge electrodes and deflection electrodes, are prevented by encasing the components in a pressurized box.
