Abstract

In Xerox 9000 family copiers, a problem of spot development was noted. Over time the number of spots increased, until a service call was required to clean the photoreceptor. In these copiers, an oil wetted fuser is closely spaced to the cleaning housing. It is believed that oil from the fuser caused the spot problem on the photoreceptor. It was further believed that the fuser oil traveled to the photoreceptor from the fuser through the cleaning housing.

FILTER PREVENTING PHOTO- Proposed Classification RECEPTOR CONTAMINATION BY U.S. C1.35513FU FUSER OIL

In Xerox 9000 family copiers, a problem of spot development was noted. Over time the number of spots increased, until a service call was required to clean the photoreceptor. In these copiers, an oil wetted fuser is closely spaced to the cleaning housing. It is believed that oil from the fuser caused the spot problem on the photoreceptor. It was further believed that the fuser oil traveled to the photoreceptor from the fuser through the cleaning housing.

To remedy this problem, a foam filter including a felt layer was attached to the cleaning housing generally in the path of the fuser oil travel, with the felt layer facing the fuser. A dramatic drop in spots per copy was noted in testing.
