Abstract:
1. An apparatus comprising: a fusing belt configured to rotate about an axis of rotation; at least one fusing belt support roller, where the fusing belt is entrained on the fusing belt support roller; a pressure roller in contact with the fusing belt to form a fusing nip, where the pressure roller and the fusing belt are configured to fuse an image on a media sheet in the fusing nip; a belt position changing mechanism configured to move the fusing belt axially in a first direction and in a second direction opposite the first direction relative the axis of rotation; and a belt position changing control module coupled to the belt position changing mechanism, the belt position changing control module configured to axially move the fusing belt periodically and regularly back and forth in a first direction and a second direction along the axis of rotation, where the first direction is opposite from the second direction, and configured to change an axial location of a change in direction from the first direction to the second direction so the fusing belt changes direction from the first direction to the second direction at different axial locations.
