1. Model Name:  MX-M850/M950/M1100 
 
2. Symptom:    Uneven charge may cause streaking in an image (paper feeding 
direction). 
 
3. Description:  We have taken countermeasures for coating strength enhanced by a newly 
adopted measure of gold-plating for charger wires to prevent the coat from 
peeling-off caused by cleaning which occurred in pre-changed charger wires in the 
past. With this fix, we intend to make an improvement against smears with the 
toner and thereby to reduce the uneven charge. 
In accordance with the modification, we have changed the coating Grid HC with 
teflon instead of the gold-plating, aiming at achieving higher performance of Grid 
HC, because there was no influence to the uneven charge by doing so. 
The way to distinguish the new part from the old one: 
A new part of charger wire is packed in a translucent blue colored package, which 
was packed in a transparent package in the past. 
A new part of Grid HC is packed in a silver colored package, which was packed in a 
gold colored package in the past.
