Abstract
A reproduction apparatus having a station for fusing images to a receiver sheet with a heated fuser roller has a release agent management system that uses an anilox roller. The anilox roller is made of metal or ceramic or other material and has a number of metering cells for holding release agent material. A doctor blade wipes excess material from the anilox roller and a donor roller picks up the metered amounts of release agent and applies the release agent to the heated fuser roller. The release agent prevents offset of the image to the fuser roller and promotes the easy separation of a receiver sheet from the fuser roller.
Claims15
For use with a reproduction apparatus with process stations for forming a toner particle image on a receiver sheet and fusing said image to said receiver sheet, wherein the fusing station includes a fuser roller heated to a sufficient temperature to fuse toner to the receiver sheet, and a release agent metering station to apply a release oil to said fuser roller to substantially prevent toner particle offset thereto, said release agent metering station comprising:
- a reservoir for holding a supply of release agent material;
- an anilox roller, associated with said reservoir, having a surface with a plurality of metering cavities for holding metered amounts of release agent material from said reservoir;
- and
- a donor member disposed in contact with said anilox roller and the fuser roller for transferring said metered amounts of release agent from said anilox roller to the fuser roller.
An electrostatographic reproduction process and release agent metering method to prevent toner particles from offsetting to a fuser member, comprising the steps of:
- charging and selectively discharging a charge retentive member to create a latent image on the charge retentive member;
- applying toner particles to the charge retentive member to develop the latent image;
- transferring the developed image to a receiver sheet and fusing the transferred, developed image to a receiver sheet wherein a fuser member is heated to a sufficient temperature to fuse toner to the receiver sheet;
- holding a supply of release agent material;
- passing an anilox roller with a plurality of metering cavities through the supply of release agent material in order to withdraw metered amounts of release agent material;
- and
- transferring the metered amounts of release agent to the fuser roller.
