OXYGEN INHIBITION FOR UNINTERRUPTED OPERATION OF PRINTHEADS Russian patent published in 2015 - IPC B41J2/01 

FIELD: printing.

SUBSTANCE: printing device comprises a nitrogen generator designed for separating the ambient atmospheric air to the first component and the second component. The first component comprises an oxygen component that comprises oxygen in a higher concentration than the ambient atmospheric air, and the nitrogen component that comprises nitrogen at a lower concentration than the said ambient atmospheric air. The second component comprises a substantially pure nitrogen component. The printing device comprises flow print assembly of ink jet printing. The flow print assembly comprises a region of oxygen inhibition. The printing area is located in the flow line after the said area of the oxygen inhibition, at that the printing area comprises a unit of printheads. The area of inertisation is located in the flow line after the said printing area, and the said area of inertisation comprises the applicator of nitrogen. The curing area is located in the flow line after the said applicator of nitrogen, and the said area of curing comprises a curing radiation lamp.

EFFECT: conveying surface is designed for providing the support for the carrier and for transportation of the said carrier through each of the said flow print assemblies of ink jet printing and for transporting the carrier through the area of the oxygen inhibition.
