    摘要: Systems and methods are provided for enhanced dryers for printing systems. One embodiment is an apparatus that includes a dryer for a continuous-forms printing system. The dryer includes heating elements located within an interior of the dryer that radiate infrared energy onto a web of printed media as the web travels through the interior, and an air knife that is interposed between the heating elements. The air knife includes a shell that directly absorbs infrared energy from the heating elements and also defines a passage for air to travel through the air knife onto the web. The shell directly absorbs infrared energy from each heating element that would otherwise overlap on the web with infrared energy from another heating element.

    摘要: 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.
