1. Change in the electro-magnetic clutch of the paper feeding unit carried out as a
measure to improve productivity.
1.Model Name: SF-2116/ 1016/21 18/1018/2020/1020/2120/1 120
2.General: A change has been carried out in the electro-magnetic clutch of the paper feeding unit
in the models listed above. This change has been carried out as a measure to improve
productivity.

Note: As shown in the figure above, the old clutch and E7 are comparable with the new
clutch and the clutch bushing, and therefore an old/new interchangeable
relationship has been established.
Note: As shown in the figure above, line processing direction is different between the old
parts and the new parts.
3.Action: From 1997 February production.

2. Measure to strengthen the clam shell lock.
1.Model Name: SF-2116/ 1016/21 18/1018/2020/1020/2120/1 120
2.General: When inserting the ADU in the SF-2020, there was a danger of the lock of the machine
becoming loose, causing the possibility of problems of clam shell opening. As a
measure to alleviate this problem, a change has been carried out in the diameter of the
lock lever spring, to improve the load of the spring. The change has also been carried
out in the springs of the other models listed above to establish interchangeability.
3.Action: ∗1 SF-1120/ 2120: From 1996 November production.
Other models: Japanese domestic production:
Running change from 1997 March production.
Chinese (SOCC) production:
Running change from 1997 April production.
French (SMF) production:
Running change from 1997 May production.
3. Measure carried out to improve problems of noise.
1.Model Name: SF-2020/1020/2120/1 120
2.General: A core, gasket and capacitor has been added to the models listed above. This measure
has been carried out to improve problems of noise.

3.Action: From 1996 mid-November production.
4. Measure carried out to improve problems of rising temperatures in the DC PWB.
1.Model Name: SF-2020/1020/2120/1 120
2.General: A change has been carried out in the models listed above as a measure to prevent the
temperatures in the DC PWB from rising. The straightening bridge diode has been
change to a shot key type which has a small electrical power consumption (low
temperature).
3.Action: From 1996 October production.
5. Measure carried out to improve problems of noise.
1.Model Name: SF-2020/2120
2.General: A reactor has been added to the models listed above. This action has been carried out
as a measure to improve problems of noise.
