1. Model Name: 
 MX-3500N/3501N/4500N/4501N, MX-450HK/450LH/450FU/450FU1/450FU2 
 
 
2. Symptom: 
The rattling of Lower heat roller bearing used at the lower heater roller shaft of the fusing unit 
may cause an abnormal sound. 
 
3. Description: 
In models such as MX-6201N and MX-7001N, the abnormal sound resulting from the rattling of 
the Lower heat roller bearing is eliminated by changing the shape of the roller stopper 
securing the Lower heat roller bearing of the lower heater roller shaft. (Before change: Roller 
stopper 
 After change: L HR C ring) 
This time, this countermeasure has also been taken for the above models. 
In T/R No. CCE-388, the Lower heat roller bearing is changed and heat-resistant grease 
(Barrierta grease) application is added. To further enhance countermeasures for abnormal 
sound, this countermeasure has been taken.
