Abstract
A drum (10) and thermal control system (180) in this disclosure are suitable for use in systems for thermally processing imaging media. The drum comprises a cylindrical surface (11) disposed around and parallel to an axis of rotation (A) of the drum, end plates (12) each extending orthogonally to the axis of rotation of the drum, and lamp heaters (14A-14B) extending parallel to the axis of rotation within the interior of the drum. By making use of thermal sensor measurements, the lamp heaters may be controlled to maintain a uniform dmm surface temperature.
