Fuser Release Evaluation

The toner-release property of an elastomeric material, intended for us in the hot roll of a xerographic hot roll fuser, is tested.

The elastomeric material 10 to be tested is permanently bonded to a small steel plate 11. The exposed surface 12 of material 10 is treated so as to model exactly the fuser' s hot roll fusing surface. A thin, uniform layer of xerographic toner powder is then applied to surface 12, and a strip of paper 13 is placed on top of the toner layer. A weight is placed on the paper. The assembly is then baked in an oven to simulate the time, temperature and pressure of the fuser's fusing nip.

The assembly is then removed from the oven, and steel plate 11 is placed in jaws 14 of a force-measuring device, such as an INSTRONT Trademark of Instron Corporation.

The piece of paper 13 is doubled back upon itself, and is clamped in jaws 15. The force necessary to peel paper 13 away from surface 12 is a measure of the elastomer's release property. The lower the force, the better the release property.

This method can also be used to test various toners, as the paper grade and elastomer are kept constant.
