Detection Timing
If a given period of time has elapsed during
warming-up, the surface temperature of the
Upper Fusing Roller does not reach:
• 50°C within 30 seconds;
• 100°C within 40 seconds after it has reached
50°C; or
• 160°C within 40 seconds after it has reached
100°C.
• Warm-up is not completed within 40 seconds
after exiting energy saver mode.
The copier does not complete its warming-up
cycle within 40 seconds after the above surface
temperature has reached 160°C.
The surface temperature of the Upper Fusing
Roller remains 120°C or less for a continuous 5-
second or more period after the copier has
warmed up.
The surface temperature of the Upper Fusing
Roller remains 230°C or more or the tempera-
