4) Manually turn the copy lamp unit/No.2/3 mirror unit drive gear to
bring No.2/3 mirror unit into contact with No.2/3 mirror unit
positioning plate. When No.2/3 mirror unit makes contact with No.2/3
mirror unit positioning plate in the rear frame side simultaneously, the
mechanical parallelism of No.2/3 mirror unit is proper.
If one side of No.2/3 mirror unit makes contact with No.2/3 mirror unit
positioning plate and the other side does not, the parallelism is
improper.
If the parallelism is improper, perform the procedure of step 5).
5) Loosen the copy lamp unit/No.2/3 mirror unit drive pulley setscrew in
the side where No.2/3 mirror unit does not make contact with No.2/3
mirror unit positioning plate.
6) Without moving the copy lamp unit/No.2/3 mirror unit drive pulley
shaft, manually turn the copy lamp unit/No.2/3 mirror unit drive pulley
in the same direction of the loosened setscrew.
When it makes contact with No.2/3 mirror unit positioning plate,
tighten and fix the setscrew.
7) Manually turn the copy lamp unit/No.2/3 mirror unit drive gear to
bring No.2/3 mirror unit into contact with the positioning plate, and
perform the procedure of step 4).
Repeat procedures of steps 4) to 7) until the parallelism of No.2/3
mirror unit is properly set.
8) With No.2/3 mirror unit positioning plate in contact with No.2/3 mirror
unit, bring the copy lamp unit into contact with the right frame and fix
the copy lamp unit to the drive wire.
Procedures 1) to 8) are for adjustment of mechanical horizontal
parallelism. The copy lamp unit and No.2/3 mirror are fixed to the
specified positions and the mechanical horizontal parallelism of
No.2/3 mirror is adjusted.
Then the optical horizontal parallelism must be adjusted in the
following procedures.
Set screw
Scanner unit drive pulley
Copy lamp unit projection
