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.

When the print preparation request is received during wait time, the control described below is performed.

Increases the speed of the fixing motor in phases (1/4 speed to 1/2 speed and then to normal speed).

Performs the start-up current control.

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)

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.

9.2.2 Down Sequence

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.
