iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
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 220 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.
No operation is performed when the power is turned on or the sleep mode is released.
9.2.2 Down Sequence
0018-9773
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
Down sequence is to prevent the machine from operating when the temperature of the end portion of the fixing film exceeds a specific temperature as when using
small-size paper continuously. The details of the control are described below:
The sub thermistor detection temperature is 275 deg C or more. Reduces the number of sheets passed by increasing the paper interval.
Returns the number of sheets to the normal when the sub thermistor detection temperature is 265 deg C or less.
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.
T deg C = 200 deg C (iR3245/3235/3230) / 190 deg C (iR3225)
4)
Starts feeding in the case of printing in plain paper mode.
Starts feeding when 5 sec have passed after the machine reached the target temperature in the case of printing in special paper mode.
