If the thermistor detection temperature is less than 100 deg C when the power is turned on or the sleep mode is released, the control described below is performed.
1. Increases the speed of the fixing motor in phases (1/4 speed to 1/2 speed and then to normal speed).
2. Performs the start-up current control.
3. Performs the temperature control at 200 deg C for 10 sec.
4. Stops the fixing motor. When the fixing motor is stopped, the fixing temperature control is also stopped, and the machine enters the stand-by mode.
When the print preparation request is received during wait time, the control described below is performed.
1. Increases the speed of the fixing motor in phases (1/4 speed to 1/2 speed and then to normal speed).
2. Performs the start-up current control.
3. Starts measuring the time passed after the machine reaches the target temperature T deg C.
Target temperature T deg C = 200 deg C (iR3570/iR4570): 190 deg C (iR2270/iR2870)
4. Starts feeding in the case of printing in plain paper mode.
5. Starts feeding when 5 sec have passed after the machine reached the target temperature in the case of printing in special paper mode.
