Abstract
An inkjet printing system includes: a printhead positioned over a media feed path; and an aerosol extractor positioned downstream of the printhead relative to a media feed direction. The aerosol extractor includes: an air knife having a knife slot for directing a flow of air towards print media; and a suction nozzle positioned upstream of the knife slot for directing aerosol into a suction channel.
Claims20
An inkjet printing system comprising:
- a printhead positioned over a media feed path;
- and
- an aerosol extractor positioned downstream of the printhead relative to a media feed direction,
- wherein the aerosol extractor comprises:
- an air knife having a knife slot for directing a flow of air towards print media;
- and
- a suction nozzle positioned upstream of the knife slot for directing aerosol into a suction channel.
An aerosol extractor for an inkjet printing system, the aerosol extractor comprising:
- a housing having a vacuum port and an air inlet port;
- an air knife in fluid communication with the air inlet port, the air knife having a knife slot for directing a flow of air towards a media feed path;
- a suction chamber in fluid communication with the vacuum port;
- and
- a suction nozzle positioned higher than the knife slot relative to the media feed path for directing aerosol into the suction chamber via a suction channel,
- wherein a curved guide surface interconnects respective sides of the knife slot and the suction nozzle, the guide surface curving away from the media feed path towards the suction nozzle.
A method of extracting aerosol in an inkjet printing system, the method comprising the steps of:
- disrupting aerosol associated with moving print media using an air knife directing a flow of air towards the moving print media;
- and
- extracting the disrupted aerosol upstream of the air knife relative to the moving print media.
