Smooth Fuser Hot Roll Has Good Print Release at Low Oil Rate

Disclosed is a means to minimize the amount of oil on print for a wet release fusing process.

Wet release fusing systems use an oil, such as silicone, to assist the release of toned prints from the hot roll. The oil is uniformly applied to the hot roll by a wicking system (see figure) consisting of a compliant, porous wick material, a holding fixture, a loading mechanism, and an oil supply. In this system, the proper oil saturation level in the wick is maintained by matching the oil input rate from the reservoir to the oil removal rate due to the hot roll. When the hot roll surface roughness is made less than 50 microinches (Ra), good print release is achieved at oil rates of 0.2 to 0.6 milligrams per print.

The benefits of reducing the amount of oil per print are:

- Makes it easier to write on the print with an ink pen.

- Lowers hot roll drive torque.

- Reduces oil supply costs.
