Fusing Temperature Control
• The Fusing Roller Heater Lamp is turned ON and OFF so that the surface temperature of
the Fusing Roller is maintained at a preset temperature.
• The surface temperature of the Fusing Roller is detected by converting the temperature
read by the thermistor to a corresponding electrical signal.
• When the temperature of the Fusing Roller rises to an abnormally high level, power to the
Fusing Roller Heater Lamp is shut down.
✽
Temperature reached upon completion of warm-up cycle:
35-cpm copier = 190 °C; 25/20-cpm copier = 183 °C
✽
Temperature is increased to 200 °C after the warm-up cycle has been completed.

CPM Control
• If special paper of a small size (width of 250 mm or less) is used to run a multi-copy
cycle, the temperature on the edges of the Fusing Rollers (over which no part of the
paper passes) tends to run high, which can damage the copier. To prevent this, the paper
feed interval is made greater.
• CPM control is activated when the number of copies made on special paper of the small
size, as counted with an internal counter, exceeds 30.
• If no special paper of the small size is fed through the copier for a period of 2 min. or
more, the counter is cleared, canceling CPM control.
