Abstract: A printing system is disclosed. The printing system includes a print controller and an engine controller to receive printing characteristic information from the print controller, determine one or more dryer control parameters based on the printing characteristic information and update the one or more dryer control parameters upon detecting one or more printing characteristic information changes during a printing process.

Abstract: Systems and methods for evenly heating a drum dryer of a print system. In one embodiment, the dryer is configured to rotate about an axis oriented in a lateral direction, to receive a radiant energy source disposed inside the drum that extends between each lateral end of the drum in the lateral direction, and to receive a reflective assembly inside the drum that includes an inner portion and an outer portion. The inner portion surrounds the radiant energy source and removably attaches the reflective assembly to a lateral end of the drum. The outer portion extends from the inner portion in a radial direction of the drum that is perpendicular to the lateral direction. The outer portion includes a reflective surface that reflects radiant energy from the lateral end to the central portion of the drum in contact with the web.

Abstract: 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.

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.

Abstract: A web handling system is disclosed. The web handling system includes a roller wheel including two or more rollers configured to engage a print medium, a motor to rotate the roller wheel and a controller to transmit a signal to the motor indicating which of the two or more rollers are to engage the print medium.

Abstract: Systems and methods for concentric arrangement of web conditioning modules in a dryer of a printing system. In one embodiment a dryer includes a drum, first rollers positioned in an arc around the drum to define a web path between an entrance of the dryer and the drum, and second rollers positioned along the arc between the first rollers and the drum that reverse the web path between the drum and an exit of the dryer. The dryer further includes first web conditioners positioned along the arc and beyond the first rollers from the drum that direct energy toward a portion of the web path that is between the entrance of the dryer and the drum. The dryer further includes second web conditioners positioned along the arc between the second rollers and the drum that direct energy toward a portion of the web path that wraps around the drum.

Abstract: Embodiments described herein provide rollers that cool a print medium downstream of a dryer while minimizing the temperature differentials across the print medium. In some embodiments, air is directed through the interiors of different rollers in opposing directions based on a pattern to reduce the temperature differential across a width of the print medium. In other embodiments, a controller alternates a direction of the air through the interior of a roller to reduce the temperature differential across the width of the print medium.
