1475161 Temperature control XEROX CORP 5 July 1974 [5 July 1973] 29886/74 Heading G3R The temperature at the nip between two rollers (130, 140) in an electrographic fusing apparatus Fig. 1, (not shown) is controlled by heating one or both rollers in dependence on the combined output of two temperature sensors, one associated with each roller. In Fig. 4, the sensors are thermistors 201, 205 connected in parallel and the illustrated circuitry governs the power supply to a single electric heater 235 located inside one of the rollers. |
