2.Description:
1. To improve productivity, we have changed the resin clip to the E ring.
Along with this change, we have changed the shape of E ring installation location of the
return roller shaft (change of groove width from 1 mm to 0.68 mm). Due to this groove width
change, use the resin clip for the old-type return roller shaft and the E ring for the new-type
return roller shaft.
Also, we haven't set parts code for the pre-change return roller shaft but have set parts code
for the new-type (post-change) return roller shaft.
2. To achieve commonality with other models and improve productivity, we have abolished
unnecessary parts in the process drive unit of the process drum BK unit.
3.Action:
         1. From July 2007 production
2. From January 2008 production
