Abstract
Systems and methods for evenly heating a drum dryer of a print system. In one embodiment, the dryer is configured to rotate about an axis oriented in a lateral direction, to receive a radiant energy source disposed inside the drum that extends between each lateral end of the drum in the lateral direction, and to receive a reflective assembly inside the drum that includes an inner portion and an outer portion. The inner portion surrounds the radiant energy source and removably attaches the reflective assembly to a lateral end of the drum. The outer portion extends from the inner portion in a radial direction of the drum that is perpendicular to the lateral direction. The outer portion includes a reflective surface that reflects radiant energy from the lateral end to the central portion of the drum in contact with the web.
