3-2) The 1st transfer follower roller AS and the bearing were discrete parts. We have 

changed the assembly of these parts so that the bearing is now pressed into the 1st 
transfer follower roller AS. This change reduces the load on the middle transfer belt by 
ensuring that the bearing will not come out and that there is no pressure pulling 
outwards on the belt. 
We have also changed the shape of the follower roller collar because the bearing was 
pressed into the 1st transfer follower roller. 
 
 

 

 

 
3-3) The tension roller AS and the bearing were discrete parts. We have changed the 

assembly of these parts so that the bearing is now pressed into the tension roller AS. 
This change reduces the load on the middle transfer belt by ensuring that the bearing 
will not come out and that there is no pressure pulling outwards on the belt. 
We have also changed the shape of the tension roller collar because the bearing was 
pressed into the tension roller. 
(This time, the shape of the tension roller collar need not be changed for 

MX2600N/3100N because the bearings used in these models differ in material and 
shape. For this reason, we have changed the shape of the tension roller collar only for 
MX-4100N/4101N/5000N/5001N.)
