ABSTRACT:
An apparatus (100) and method (500) that controls the change of direction of a fusing belt in a printing apparatus is disclosed. The apparatus can include a fusing belt (120) configured to rotate about an axis of rotation (128). The apparatus can include at least one fusing belt support roller (131) where the fusing belt can be entrained on the fusing belt support roller. The apparatus can include a pressure roller (132) that contacts the fusing belt to form a fusing nip (137), where the pressure roller, the heater, and the fusing belt can be configured to fuse an image on a media sheet (112) in the fusing nip. The apparatus can include a belt position changing mechanism (150) 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. The apparatus can include a belt position changing control module (152) coupled to the belt position changing mechanism. The belt position changing control module can be 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.
