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.
