ELIMINATION OF ABNORMAL RATTLING SOUND FROM 
FUSING UNIT’S TOP HEAT ROLLER BEARINGS.

1. Model Name: 
  MX-3500N/3501N/4500N/4501N, MX-450HK/450UH/450FU/450FU1/450FU2 
 
2. Symptom: 
Looseness in the fusing unit’s top heat roller shaft sometimes produces an abnormal rattling 
sound. 
 
3. Description:
 
In technical bulletin 078, countermeasures were taken by adding four HR spacers to the front 
and one HR spacer to the rear of the top heat roller. In order to further improve upon these 
measures, an additional undulate washer has been added to both the front and rear of the top 
heat roller to eliminate rattling bearings. 
Additionally, as part of these measures, two HR spacers have been removed from the top heat 
roller; one each from the front and the rear. 
Note: If these measures fail to eliminate the rattling sound in the field, this may be due to wear 
on the top heat roller and the top heat roller bearing. In this case, the top heat roller and 
the top heat roller bearing should be replaced.
