ABSTRACT:
Apparatuses useful in printing and methods of controlling the temperature of surfaces in apparatuses useful in printing are provided. An exemplary embodiment of the apparatuses useful in printing includes a belt including a first surface; at least one heat source for heating the first surface; a roll including a second surface; a temperature sensor positioned to measure a temperature of the second surface; and a roll positioning device coupled to the roll for positioning the second surface of the roll in contact with the first surface of the belt to form a nip and increase the temperature of the second surface, and for positioning the second surface out of contact with the first surface to decrease the temperature of the second surface, in response to the temperature measured by the temperature sensor.
