1. Trouble shooting dislocation of the dark box cover during shipping.
1.Model name: SF-2114/ 2214
SN-1420/1430 (only for machines bound for the USA).
2.General: The cover of the dark box sometimes becomes dislocated from the lens drive shaft in
the optical unit while the machines are being shipped. To alleviate this problem, the
measures described below have been carried out.
3.Description: A groove has been added to the lens drive shaft, and after inserting the drive shaft
through the dark box cover a plastic E-ring has been attached to prevent the dark box
cover from becoming dislocated.

2. Trouble shooting white-outs during half-tone copy operations.
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (only for machines bound for the USA).
2.General: White-outs sometimes occur in the TC case section during half-tone copy operations
when they are carried out during periods of low humidity or other weather conditions
conducive to the occurrence of static electricity. To alleviate this problem, the
improvement measures described below have been carried out (no problems have
occurred during normal text copy operations).
3.Description: To alleviate the problem described above, a change has been carried out in the shape
of the AC guide attached to the TC case.

3. Trouble shooting shaft bushing dislocation of the paper winding drive shaft.
1.Model name: SF-2014/21 14/2214
Z-800, SN-1420/1430 (only for machines bound for the USA).
2.General: The paper winding drive shaft in the optical unit is supported by a shaft bushing
attached to the frame. The possibility exists that the shaft bushing might become
dislocated during shipping due to the lack of connection allowance for the shaft bushing
when surrounding parts are clustered together. To alleviate this problem, the
improvement measures described below
have been carried out.
3.Description: <Temporary measure>
As shown in the figure to the right, a washer
has been added between the E-ring and the
shaft bushing to prevent the shaft bushing
from becoming dislocated.

been carried out.
For China (SOCC) production only: This change was carried out during the period from
1995 mid-June production to 1995 July production.
<Permanent measure>
In order to increase the shaft bushing allowance with the optical bed plate, the shaft
bushing has been changed to a longer one.
(Old) (New)
When the new, longer shaft
bushing is used, the washer
used in the temporary
measure described above
become unnecessary.

2.General: A white mylar sheet has been attached to the upper paper guide of the SPF slit (slit
upper paper guide mylar) as a counter measure for black streaks which occur during
reduction copy operations carried out using the SPF.
