  • Electromechanically operated fuser roll closure
    Patent number: 4392739
    Abstract: A fuser roll apparatus in a toner fixing station associated with an electrophotographic or xerographic device for fixing a toner image onto a copy sheet by the application of heat and pressure. The fusing apparatus includes a pair of fuser rollers and a linkage mechanism coupling a control cam and the fuser rollers. An electromechanically operated latch, in the form of a solenoid, is interposed in the linkage mechanism coupling the control cam and fuser rollers. So long as the solenoid is energized, the opening of the rollers is controlled solely by the rotation of the cam. If the solenoid is deenergized however, the rollers are maintained in an open position. Thereafter, until the solenoid is again energized, the rollers remain open and are unaffected by rotational movement of the cam.
