ABSTRACT:
An aerosol reduction system collects stray ink aerosol generated by inkjet printheads includes ventilation and collection components. During printing and purging, the printhead ejects ink to generate a desired ink droplet and a by-product comprising floating ink satellites. The aerosol collection system may be either passive or active, with the passive devices relying upon carriage motion to bring the collection elements into contact with the aerosol collection location. The passive systems have collection elements mounted on the carriage, including a rigid electrostatic filter, a billowing sail shaped filter geometry, or electrically charged plates. The active systems use some additional mechanism to bring the aerosol and the collection location together, such as the carriage-mounted aerosol removal or extraction fans illustrated. The collection location of these active systems may be mounted at the carriage, or well behind the carriage.
