Detection Timing
• The surface temperature of the Fusing Roller does not
reach a given level even after the lapse of a given period
of time during a warm-up cycle.
From room temperature to 100°C:
From 100°C to 140°C:
From 140°C to the completion of
the warm-up cycle:
• The Fusing Roller Thermistor does not detect a prede-
termined temperature within 30 sec. after a warm-up
cycle has been started and thus the warm-up cycle is
not completed.
• The surface temperature of the Fusing Roller does not
reach a given level even after the lapse of a given period
of time during a warm-up cycle.
From room temperature to 60°C:
From 60°C to 100°C:
From 100°C to 130°C:
From 130°C to 155°C:
• The Fusing Roller Sub Thermistor does not detect a
predetermined temperature within 30 sec. after a warm-
up cycle has been started and thus the warm-up cycle is
not completed.
• The surface temperature of the Fusing Roller does not
reach a given level even after the lapse of a given period
of time during a warm-up cycle.
From room temperature to 60°C:
From 60°C to 100°C:
From 100°C to 130°C:
From 130°C to 155°C:
• The temperature detected by the Fusing Roller Ther-
mistor remains lower than 120°C (105°C for the model
having two Fusing Roller Heater Lamps) for a given
period of time during the standby state.
• The temperature detected by the Fusing Roller Ther-
mistor remains lower than 120°C (105°C for the model
having two Fusing Roller Heater Lamps) for a given
period of time during a print cycle.
• The temperature detected by the Fusing Roller Sub
Thermistor remains lower than 105°C for a given period
of time during the standby state.
• The temperature detected by the Fusing Roller Sub
Thermistor remains lower than 105°C for a given period
of time during a print cycle.
• The temperature detected by the Fusing Roller Ther-
mistor remains higher than 240°C for a given period of
time.
