POOR ADHESION CAUSED BY INSUFFICIENT APPLICATION 
OF PRESSURE FROM UPPER AND LOWER HEAT ROLLERS.

1. Model Name: 
  MX2600N - MX3100N 
 
2. Symptom:
 
When the upper and lower heat rollers return from a pressure release state to a pressure 
application state, in rare cases, the cams do not return sufficiently and thereby the pressure is 
not applied enough to secure the adhesion. Rubbed by fingers, the print may get blurred. 
 
3. Description:
 
The following parts changes have been implemented so that the upper and lower heat rollers 
can generate sufficient pressure when they return from a pressure release state to a pressure 
application state. 
 
- Pressure release joint shaft (One parallel pin hole is horizontal, while the other is now 
angled 5  from the horizontal.) 
 
 
- In order to reduce the amount of play in the holes for the pressure release joint shaft and 
the grooves for the parallel pin in the release joint gears and release levers F and R, 
tolerances for the holes and grooves have been reduced. 
 
 
 
 
 
 
Note 1: Check the position of the release lever F and R, when the release joint gear 
(24T) is fitted to the joint shaft fixing plate in the fusing unit. See below. 
 
 
 
1. Fit the release joint gear (24T) to the joint shaft fixing plate in the fusing unit, 
arranging the upper line on the release lever F in a horizontal relationship with 
respect to the metal end line of the lower frame F. See Figure 1. 
2. Fit the release joint gear (24T) to the joint shaft fixing plate in the fusing unit, 
arranging the lower line on the release lever R in a horizontal relationship with 
respect to the metal end line of the lower frame R. See Figure 2. 
 
Note 2: Ensure that the numbers of teeth observed next to where the release joint gear (24T) 
and the release idle gear engage each other agree with the following numbers of 
teeth in the figures below.
