- By controlling the voltage of the power supply with
It was designed to keep the surface temperature of the cell constant at all times. Therefore, if the temperature sensor itself has low sensitivity, when the heat rule warms up,
As shown in Part 1, the surface temperature of the heat roll varies from room temperature T1 to the optimum temperature for fixing) R-low temperature T2 (R1)
It was common practice for the lamp heater of the heat rule to continue to turn on even after reaching the temperature indicated by TI(R2), and then return the temperature to the temperature indicated by TI(R2) above. Therefore, there is a drawback that the warm-up time of the heat roll becomes longer than necessary, and power is wasted during that time.
