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.Item DescriptionFixing method by fixing film + pressure rollerFixing heater plate-type heaterControl temperature 180 deg C (at PSTBY)Fixing drive control by control of fixing film speedFixing temperature detection by main thermistorProtective mechanism by sub thermistorCleaning method by cleaning roller[1][2][3][4][5][6][7] [8]
