1. Model Name: 
  MX4100N – MX5000N – MX4101N – MX5001N 
MX310B1 – MX310U1 - MX410U1 
 
2. Description:
 
To prevent bead erosion (the shoulders installed at the edge of F/R on the back of the 1st 
transfer belt), blade inversion, poor cleaning performance and belt breakage from occurring in 
the 1st transfer unit, we have taken the following countermeasures: 
 
1. To prevent bead erosion from occurring in the middle transfer belt, we have changed the 
bead material. 
 
Bead before change : White translucence      Bead after change : Black 
 
2. To prevent poor cleaning performance and blade inversion from occurring in the 1st transfer 
cleaner unit , we have changed the cleaning angle of the 1st transfer blade from 11.3 to 9.2 
and the linear pressure from 2.34 to 2.9. 
 
 
 
 
 
3. To prevent the middle transfer belt from being broken, we have changed the following three 
items: 
 
3-1) To reduce the load placed on the middle transfer belt, we have changed the load of the 
belt tension spring from 3,000 g to 2,100 g. 
(For MX-2600G/2600N/3100G/3100N, the load of the belt tension spring is already 
changed from the 1st lot production, so this time we have changed the load for MX-
4100N/4101N/5000N/5001N.)

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.)
