1. MEASURE TO PREVENT PROBLEMS OF THE BUSHING OF THE REVERSION DRIVE SHAFT BECOMING
DISLOCATED.
2. MEASURE TO PREVENT PROBLEMS OF IMPROPER LOCKING OF THE ADU TRANSPORT GUIDE UNIT.
3. MEASURE TO IMPROVE THE ON/O FF POI NT OF THE POD SENSO R.
4. MEASURE TO ESTABLISH INTERCHANGEABILITY OF THE CLOSING LABEL OF THE MACHINE.
No. : SP-2112
1. Measure to prevent problems of the bushing of the reversion drive shaft becoming
dislocated.
1.Model Name: SF-2120/1 120
2.General: There have been problems reported in the upper paper delivery cabinet of the models
listed above of the bearings which support the reversion drive shaft and reversion
rollers becoming dislocated due to sagging of the delivery plate. As a measure to
alleviate these problems, the method of inserting the reversion drive shaft bearings has
been reversed, in order to prevent the sagging of the delivery plate, and thus prevent
the bushing from becoming dislocated. In accordance with this change a change in the
shape of the reversion drive shaft has also been carried out.
Discontinued
Tightened from the inside
When carrying out the action described above on machines produced before 1996
December production lots, the new reversion drive shafts which have had the change in
shape carried out should be used.
3.Action: From 1996 December production.

2. Measure to prevent problems of improper locking of the ADU transport guide unit.
1.Model Name: SF-2120/1 120
2.General: There have been problems reported in the ADU transport guide unit in the base plate
unit of the models described above of improper locking caused by deviation in the lock
load. As a measure to alleviate these problems a change in the magnet catch has been
carried out.

3.Action: From 1996 December production.
3. Measure to improve the ON/OFF point of the POD sensor.
1.Model Name: SF-2116/ 1016/21 18/1018/2020/1020/2120/1 120
2.General: The margin of the ON/OFF point of the sensor was too small when installing the POD
actuator in the models listed above, making it difficult to maintain control with the
change in the metal of the attachment plate. As a measure to alleviate this problem an
actuator guide has been added in the fusing unit to improve the movement of the POD.
