SUBJECT: SC520
SYMPTOM:
SC520 appears during a long copy run.
CAUSE:
The fuser lubricant may become viscous during a long copy run.
SOLUTION:
To prevent this, the production machines have been modified as follows:
1. The material of the bushing has been changed.
2. The bushing has been assembled from the inside of the holders.
3. The retaining rings have been removed and the grooves for the retaining rings on the lower cleaning
roller have been eliminated.
NOTE: 1. The old lower cleaning roller is no longer available.
2. These (new style) parts are available as an assembly (A0974242).
