iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
There are 2 types of speed to control the heat exhaust fan (rear) (FM1) and heat exhaust fan (front) (FM2).
Voltage switch PCB unit of each fan switches the voltage to change the speed of rotation.
F-10-4
Power supply cooling fan (FM3) drives at full-speed at paper feed and at 1/2 speed in other situations.
10.3.3 Operation sequence
0018-9985
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
1. In standby, sleep mode
In standby, sleep modes, the heat exhaust fan (front/rear) (FM2/1) and power supply cooling fan (FM3) do not drive.
2. In printing
In printing, the heat exhaust fan (front/rear) (FM2/1) drives at full speed or 1/2 speed depending on 1-sided/2sided print and temperature detected by environment
sensor (HU1).
- In 2-sided print
T-10-5
- In 1-sided print
T-10-6
Note 1: If there is 1 job of 1-sided print or more during continuous print, the machine uses control for 2-sided print.
Note 2: Printing operation continues until the rotation of fixing motor (M3) stops.
Power supply cooling fan (FM3) drives at full-speed at paper feed and at 1/2 speed in other situations.
