Abstract

This disclosure relates to a release agent management (RAM) system for applying a release agent, such as silicone oil, to a fuser roll 10 cooperating with a pressure roll 12 to fuse toner images to copy substrates. The system uses a drum 14 to deliver release agent (RA) 15 to a metering blade 16 (see Figure 1). The RA is picked up by the drum as it rotates through a sump 18 containing the RA and is scraped off the drum by a chute 20 that delivers it to the roll 10 just in front of the metering blade 16. The blade then meters a thin coating of RA onto the

fuser roll, as the excess RA 21 flows over the back of the blade assembly into the sump. The drum and chute are nearly the same length as the blade so the entire length of the blade receives a fresh supply of RA simultaneously and continuously. Hence, this system will allow a rapid delivery of RA to the entire blade on start- up. This is essential to prevent damage to the blade from tucking under caused by a dry roll condition. This system should also provide good flow at the blade tip to flush paper fibers and other foreign matter into the sump where they can be filtered out by...
