Abstract

to a wick cover for a release agent management (RAM) system for use in conjunction with a xerographic fuser. The wick cover is an oil diffusive media which contacts the fuser roll for the purpose of applying the silicone oil to the roll in the quantities necessary to maintain release. It also functions as a cleaner, removing extraneous toner, paper fibers and other con-taminents. The cover serves as the replaceable member of the wick RAM, being replaced when contamination levels accumulate to the point of reducing it's primary function of applying oil.

               to a wick cover for a release agent management (RAM) system for use in conjunction with a xerographic fuser. The wick cover is an oil diffusive media which contacts the fuser roll for the purpose of applying the silicone oil to the roll in the quantities necessary to maintain release.

The cover serves as the replaceable member of the wick RAM, being replaced when contamination levels accumulate to the point of reducing it's primary function of applying oil.

Wick covers are typically made of "needled" batts of temperature resistant fiber. These 9-teedledI1 wick covers have several deficiencies, in that under some operating conditions they tend to stretch and have fibers torn out, ultimately requiring early replacement.

Loose fibers have been observed to cause problems by building up under the pressure roll stripper finger causing paper jams. Also, there are indications that the interface between the wick and wick cover is not intimate enough to maintain adequate oil diffusion under some circumstances. The use of thin woven cloth for the wick cover material minimizes these deficiencies.
