Abstract
Apparatus for uniformly applying toner-release lubricant to, and for cleaning, heated fusing rolls used in copying or reproduction machines. The apparatus comprises a lubricant-dispensing roll containing an internal supply of lubricant; an applicator roll for transferring lubricant from the dispenser roll to the fuser roll and for wiping the fuser roll; and a spreader roll for evenly distributing the lubricant on the applicator roll prior to the completion of transfer to the fuser roll. The dispenser roll is designed to (1) dispense lubricant uniformly and substantially continuously over approximately 270.degree. of each revolution, regardless of the oil level therein, and (2) preclude the dispensing of lubricant when not in use.
