Abstract
Apparatuses useful for printing and methods of controlling a temperature of a surface in an apparatus useful for printing are disclosed. An exemplary embodiment of the apparatuses includes a first roll including a first outer surface and at least one first heating element for heating the first outer surface; a second roll including a second outer surface; a nip between the first outer surface and the second outer surface; a first temperature sensor for sensing a pre-nip temperature at a pre-nip location; and a first voltage modulator connected to each first heating element and the first temperature sensor. The first voltage modulator receives a temperature signal from the first temperature sensor indicative of the pre-nip temperature and modulates an AC voltage supplied to each first heating element to maintain each first heating element continuously ON at a power level ranging from partial power to full power to control the pre-nip temperature.
