plate hook.
2
Pass the mirror base wire along the groove outside the double
pulley.
<Note> At the time, put the No. 2/3 mirror unit on the mirror base
positioning plate.
Hold it so that the winding pulley groove is on the upper
side, and wind the wire.

Fix the mirror base wire to the pulley with the mirror base wire
fixing screw.
4
Return the 9th winding tip of the mirror base wire to the original
position. (Perform the same procedure for the front frame side and
the rear frame side.)
(Note) After replacing the mirror base drive wire, perform the vertical
skew adjustment, the focus adjustment, and the horizontal
skew adjustment.
3) No. 2/3 mirror unit (mirror base B) installation
(Mirror base B positioning)
This is to adjust the parallelism of mirror base B and the drum surface
and the original surface.
This adjustment must be performed in the following cases:
•
When the mirror base drive wire is replaced.
•
When mirror base A or mirror base B is replaced.
1
Manually turn the mirror base drive pulley to bring the mirror base
B in contact with the mirror base positioning plate. If the front side
and the rear side of the mirror base B make contact with the
mirror base positioning plate simultaneously, the parallelism of the
mirror base B is proper, and there is no further adjustment.
