160°C within 40 seconds after it has reached 100°C.
*
The surface temperature of the Upper Fusing Roller does not reach
200°C within 40 seconds after it has reached 160°C.
b) C0510: Abnormally Low Fusing Temperature
*
The surface temperature of the Upper Fusing Roller remains 135°C or
less for a consecutive 1-second period after the copier has completed
