| 1. A method of generating a desired first temperature profile on an outside surface a hot fusing roller, the method comprising:
(a) heating an inside surface of the hot fusing roller;
(b) measuring a plurality of locations on the outside surface of the hot fusing roller to determine a second temperature profile;
(c) applying a heat absorption material differentially across the inside surface of the hot fusing roller based on a difference
between the second temperature profile and the desired first temperature profile;
(d) measuring the plurality of locations on the outside surface of the hot fusing roller to determine a third temperature
profile;
(e) determining if the third temperature profile is substantially the same as the desired first temperature profile; and
(f) performing steps (a) through (e) based on determining that the third temperature profile is not substantially the same
as the desired first temperature profile.
