Abstract
The turbulence of the air moved through an inkjet print head enclosure is reduced before reaching the printing region between the print head and a print medium by positioning a HEPA filtration system between an air inlet opening in the enclosure and the print head. Turbulence is removed from air moved through the air path by HEPA filtration of the air being drawn into the print head enclosure before reaching the printing region.
Claims6
An inkjet print head system comprising:
- an enclosure having an air inlet opening;
- a fan adapted to move air into the enclosure through the air inlet opening;
- a print head adapted to eject fluid droplets through a printing region between the print head and a print medium, wherein the printing region is exposed to air being moved in the enclosure by the fan;
- a HEPA filtration system positioned between the fan and the printing region such that turbulence in the air moved through the air inlet opening is reduced by the HEPA filtration system before reaching the printing region;
- a manifold through which air flows into the print head, said manifold being located within the enclosure;
- and
- a replaceable non-HEPA filter is associated with the manifold.
