Abstract:
A system for varying an amount of thermal energy transmitted to print media advancing along a print oath in a printing device, comprising:a heater configured to produce thermal energy; a thermally conductive endless belt, rotatably carried by the printing device and configured to transmit thermal energy from the heater to the print media, at least a portion of said belt being disposed adjacent the print path along at least a portion thereof, a length of said belt portion adjacent the print path being adjustable so as to vary the amount of time print media advancing along the print path is adjacent said belt; and a first roller about which said belt turns, the first roller being movable parallel to the print path to vary the distance along the print path where said belt is adjacent the print path; whereby the amount of thermal energy transmitted to print media traveling along the print path is adjustable.
