The fixing temperature sequence and the heater (main/sub) control sequence are continued over the distance.
2. If the distance is 60 sec or more
The fixing temperature control sequence and the heater (main/sub) control sequence are performed over the distance
up to 60 sec; thereafter, only the heater sequence control is performed.
