Abstract
A fuser apparatus includes fuser and pressure rolls rotatably mounted parallel to and in contact with each other to form a nip through which print media with a toner image thereon is passed to fuse the image to the print media. A heating lamp is positioned to heat the fuser roll. A mechanism is used that alters the interior of a fuser housing to harvest the excess heat emitted by the heating lamp and to reflect the excess heat back to the fuser roll at different patterns/angles dependent on the mode of the fusing and the size of print substrate being marked.
