REF: ARE 994 PREVENTION OF UPPER HEAT 
ROLLER DAMAGE. 
 
1.Model Name: 
MX-M623U/M753U 
 
2.Description: 
As an improvement against the upper separate pawl causing damage to the upper heat roller of
  
the fusing unit and to allow variations in the mounting location for the upper separate pawl to 
other non-conventional mounting methods, the profile of the fusing rear upper PG and the 
upper separate pawl holder has been changed. 
 
To make the above changes, the profile of the screw hole of the fusing rear discharge brush 
has been changed as has the thickness of the sheet (from 50µm to 100µm) where the screw 
hole of the fusing rear discharge brush is. Due to this, the waser normally used with this screw 
is no longer required. 
 
Since a washer is no longer required, the screw of the fusing rear discharge brush F/R has also 
been changed from "XBBS740P06000" to "XBPS740P06000".
