19-3. Fusing Temperature Control
• The Fusing Roller Heater Lamp is turned ON and OFF to keep a set temperature on the
surface of the Fusing Roller.
• The Fusing Roller surface temperature is detected by using a thermistor that translates
the temperature to a corresponding electrical signal.
• If the Fusing Roller temperature becomes excessively high, the Fusing Roller Heater
Lamp is shut down.
19-4. CPM Control
• If paper of a small size (width of 250 mm or less) or thick paper is used to run a multi-
copy cycle, the temperature on the edges of the Fusing Rollers tends to run high, mean-
ing that the temperature of the Fusing Rollers varies among different spots of the rollers.
• When the cumulative number of copies made through continuous copy cycles* exceeds
30, the paper take-up interval is made longer, thereby allowing the temperatures of the
Fusing Rollers at different spots to be uniform.
✽ Continuous copy cycle: Continuous copy cycles run with an interval of 2 min. or less
between cycles.
