A controllable thermal warming device for delivering heat to an object by radio frequency signal. The controllable thermal warming device may include a thermal ink heating element comprising a substrate and a conductive ink fixedly disposed on the substrate, a power source operatively coupled to the conductive ink, the power source adapted to deliver a voltage to the conductive ink to cause the conductive ink to radiate heat, a controller operatively coupled to the power source and the conductive ink, the controller adapted to control the voltage delivered to the conductive ink and to detect an operating characteristic of the conductive ink and adjust the voltage in response to the operating characteristic, and means for controlling the controller by radio frequency. The controllable thermal warming device may also include a sensor to provide the operating characteristic to the controller.

A dryer management system includes a global dryer control system and a closed loop dynamic dryer control system to manage drying of a material deposited on web. The global dryer control system analyzes information regarding a production run to determine a web conveyance speed and a maximum web temperature. The closed loop dynamic dryer control system monitors an indication of a temperature of the web to maintain the indication of the temperature below the maximum web temperature. The closed loop dynamic dryer control system also analyzes images of the web to determine if the material is being insufficiently dried.

A method of heating a print zone disposed between a print-head and a media support device of a printing system includes supplying a first amount of power to a heating assembly to form and direct heated air in a first temperature range to the print zone of the printing system. The method also includes determining whether a temperature of the printhead is within a warning temperature range and, if so, supplying a second amount of power that is less than the first amount of power to the heating assembly to form and direct heated air in a second temperature range to the print zone. Otherwise, the first amount of power is continued to be supplied to the heating assembly.
