Figure 1 [1]Fixing Assembly [2] Upper Fixing Assembly

Cause: In normal operation, the Bushing Spacer [4] rotates together with the Upper Fixing Roller [5]. However, when the Bushing Spacer [4] does not rotate along with the Upper Fixing Roller [5], the friction created by this phenomenon may force the Bushing Spacer [4] outward. This may result in the outside area of the Bushing Spacer to detach or break from the Upper Fixing Roller [5].
