Externally heated fuser assembly for variable sized media |
| 摘要 |
A fuser assembly for an electrophotographic image forming device according to one example embodiment includes a rotatable fusing member forming a fusing nip with a backup member. A heating lamp is positioned to heat the fusing member. A first reflector is positioned around a circumferential portion of the fusing member and positioned to direct light from the heating lamp onto the fusing member. The first reflector covers a first section of an axial length of the fusing member and does not cover a second section of the axial length of the fusing member. A second reflector is movable between a first position covering at least a portion of the second section of the axial length of the fusing member and a second position uncovering at least a portion of the second section of the axial length of the fusing member. |
