Abstract:
A ""green"" rapid recovery fusing apparatus comprising:(a) a frame;(b) a moveable heated fusing member mounted to said frame;(c) a moveable pressure member mounted to said frame and forming a pressure fusing nip against said moveable heated fusing member; and(d) a thermal loss preventing enclosure surrounding said heated fusing member and having low thermal conductivity walls including thermal insulating matter therein for reducing thermal loss from said heated fusing member and enabling rapid recovery of said heated fusing member from a standby energy saving temperature to a fusing temperature higher than the standby energy saving temperature, said thermal loss preventing enclosure including an energy reflective shield mounted on an inside surface of said walls facing said heated fusing member for reflecting infrared energy from said heated fusing member back onto said heated fusing member, and seal members mounted to said low thermal conductivity walls for contacting and sealing against said moveable fusing member to trap and retain heat within said thermal loss preventing enclosure.
