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.
