OPERATING SOUND OF FUSING COOLING 
FAN IN PRE-HEAT MODE 
 
1. Model Name: MX-C250/C250E/C250F/C250FE/C300E/C300F/C300W/C300WE 
 
2. Description: 
Modification to reduce the noise due to the factor with fan has been implemented on T/R   
 
 
No. CCE-1225R.    However, we would like to inform you of the remedy below if you are   
 
 
bothered by the operating sound of fusing cooling fan in pre-heat mode even after this   
 
 
modification.    When it is required in the field, please take action accordingly. 
 
 
 
- Method to stop the fusing cooling fan when you are bothered by the operating sound of   
 
 
fusing cooling fan in pre-heat mode: 
 
  Setting 
method: 
 
 
 
Change the set value of TH_UM in pre-heat mode to "50" with Service Simulation. 
 
 
 
SIM No. 43-1   3: OTHER   7: HL_UM E-STAR  “50” 
 
  Detail 
of 
operation: 
 
 
 
Operation of fusing cooling fan (FUFM) in pre-heat mode stops when the target fusing   
 
 
temperature in pre-heat mode is set to 50-degree or lower and also the temperature   
 
 
inside the machine (temperature of duct thermistor) is under 40-degree.   
 
 
 
Note: 
 
 
For the customer who is bothered by the operating sound of fusing cooling fan,   
 
 
please configure the setting.    Since this setting decreases the target fusing temperature   
 
 
in pre-heat mode, the wake up time from pre-heat mode will be delayed depending on the   
 
 
environment of usage etc so please explain it to the customer before the setup.
