Xerox 4127 Parts:

Feature and Advantages
This kind of lower sleeves are made in China. But comparing with the original sleeves, they are of the same material and quality. They are made of sponge sleeves instead of rubber ones. Countless bubbles and eighteen uniformly distributed tubes guarantee better thermal conductivity and resilience.


Film on rubber sleeve is attached by the adhesive force between the two materals; while on sponge sleeve, film is adhered by glue imported from Japan, which is also used in original rollers. Higher thermal diffusivity, less deformation and stronger adhesion avoids film from wrinkling and  peeling.



To prevent paper from jamming and tearing, the two ends of the sponge sleeve is made bigger or smaller than the middle. But shaped by gating system, the rubber sleeve has to be straight.

Advantage:

1. Reliable thermal conductivity
2. High thermal diffusivity
2. Fine resilience
3. Little deformation
