ABSTRACT:
An air jet assisted ion projection machine including an image bearing member, an ion generator, an inlet channel and an outlet channel connected to the ion generator, a source of air in communication with the inlet channel to move ions through the outlet channel, the outlet channel being located near the image bearing member, modulation means located adjacent the outlet channel for controlling the passage of ions therethrough to the image bearing member, and an ozone filter system for filtering ozone generated within the machine, the ozone filtering system comprising an ozone filter supported within the machine, and an air path defined by the machine geometry between the outlet channel and the ozone filter, the source of air for moving ions also conveying ozone in the air path to the ozone filter.
