1.MEASURE TO IMPROVE PROBLEMS OF CRACKING OF THE
COUPLING IN THE FUSING DRIVE SECTION.

2.MEASURE TO IMPROVE PROBLEMS OF CRACKING OF THE
COUPLING IN THE MAIN MOTOR UNIT .

1. Measure to improve problems of cracking of the coupling in the fusing drive section.

1.Model Name: SD-2260

2.General: Some changes have been carried out in the assembly of the fusing drive section.

These changes have been carried out as a measure to prevent problems of cracking of
the drive coupling between the fusing drive section and the suction section. Previously
a single holding pin and an E type ring were used, but this has been changed and now
2 straight pins are being used. In accordance with these changes the coupling and the
spring have also been changed.
