ABSTRACT:
Vapour removed from the drying chamber of a hardcopy apparatus is condensed and passed to a reservoir from which it is intermittently pumped into an ink supply cartridge. Cartridge supplies ink from a first bag via a first nozzle. As the first bag contracts, it allows a second bag to expand to receive the condensate from reservoir via a valving system and a second nozzle. In addition, a pump supplies air the second bag via piping; by switching over the valving system, it is the same pump which is used to transfer the condensate from reservoir to the cartridge.
