US 10,245,853 B2 · Concentric duct system for a dryer of a printing system

Abstract

Systems and methods for concentric duct system for a dryer of a printing system. One embodiment includes a dryer of a printing system and a duct system. The dryer includes web conditioners sources to condition a web of print media, intake ports to supply air for the web conditioners, and outlet ports to remove air for the web conditioners. The duct system includes a supply hub and a return hub. The supply hub includes a tubular body with a lower portion and an upper portion, and supply nodes around the lower portion. The return hub includes a body around the upper portion of the supply hub, and return nodes around the body. The duct system further includes supply ducts to connect the supply nodes and the intake ports, and return ducts to connect the return nodes and the outlet ports.
