Abstract

This disclosure relates to a method of improving the performance of a xerographic type fuser apparatus which does not use a release agent such as silicone oil to prevent toner offset. It has been observed that performance of Ramless (i.e., without a release agent management (RAM) system) fusers is seriously affected by the presence of contaminants such as paper, fibers, clay and starches.

PAPER CLEANING ROLL Proposed James E. Mathers Classification

This disclosure relates to a method of improving the performance of a xerographic type fuser apparatus which does not use a release agent such as silicone oil to prevent toner offset. It has been observed that performance of Ramless (i.e., without a release agent management (RAM) system) fusers is seriously affected by the presence of contaminants such as paper, fibers, clay and starches.

By providing a paper cleaning station through which copy sheets pass prior to moving into the image transfer zone, the contaminants can be appreciably reduced. For this purpose, the sheets are passed between two rollers each coated with a thick layer of silicone rubber which is known to attract such contaminants. Scraper blades can be provided to remove the contaminants from the rolls. It is also contemplated that the rolls serve as a paper registration structure.
