1. Model Name: 
 MX-3500N/3501N/4500N/4501N, MX-450HK/450LH/450FU/450FU1/450FU2 
 
2. Symptom:
 
The rattling of upper heater roller bearing used at the upper heater roller shaft of the fusing 
unit may cause an abnormal sound. 
 
3. Description:
 
To eliminate the abnormal sound resulting from the rattling of the upper heater roller bearing 
of the upper heater roller shaft, we have added four HR spacers to the front side of the upper 
heater roller and one HR spacer to the rear side. (Addition of a total of five HR spacers) 
 
Aside from countermeasures for abnormal sounds from the upper heater roller shaft, we have 
also taken countermeasures for abnormal sounds from the lower heater roller shaft. Also refer 
to T/R No. CCE-338 and CCE-528.

2. Symptom:
 
The rattling of upper heater roller bearing used at the upper heater roller shaft of the fusing 
unit may cause an abnormal sound. 
 
3. Description:
 
To eliminate the abnormal sound resulting from the rattling of the upper heater roller bearing 
of the upper heater roller shaft, we have added four HR spacers to the front side of the upper 
heater roller and one HR spacer to the rear side. (Addition of a total of five HR spacers) 
 
Aside from countermeasures for abnormal sounds from the upper heater roller shaft, we have 
also taken countermeasures for abnormal sounds from the lower heater roller shaft. Also refer 
to T/R No. CCE-338 and CCE-528.
