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.
