Abstract
A system for cleaning lower print head structure of ink jet printing apparatus effects: (i) a condensation cycle wherein a droplet stream(s) are directed past such print head structure in a solvent condensing mode, (ii) a drying cycle in which air is directed across said print head structure to remove condensed solvent and (ii) a heating cycle wherein the lower print head structure is heated to a temperature obviating condensation of solvent from said stream(s).
