[8] Adjustment
1. Optical section
A. Image distortion adjustment
There are following two types of image distortion.
Horizontal image distortion
Vertical image distortion
In this machine, the image distortion is adjusted by changing the paral-
lelism of mirrors (copy lamp unit, No. 2/3 mirror unit).
(1) Horizontal image distortion adjustment
a. Summary
Parallelism of mirrors can be made by installing the copy lamp unit
and No. 2/3 mirror unit to the reference position. However, it must
be checked by making a copy, and must be adjusted if necessary.
b. Cases when the adjustment is required
1) When the copy lamp unit and No.2/3 mirror unit are disas-
sembled or their part is replaced. 
2) When the copy lamp unit and No.2/3 mirror unit drive section is
disassembled or its part is replaced. 
3) When the copy image is distorted as shown below:
c. Necessary tools
Screwdriver (+)
Hex wrench 
Scale
Test chart for distortion adjustment (Make a chart shown below
by yourself.)
Draw a rectangle on a paper (B4 or 8 1/2
″  × 14″) as shown
below.
Be sure to make four right angles. 
d. Adjustment procedure
1) Remove the right cabinet (manual paper feed unit), the docu-
ment reference plate. 
2) Remove the document glass.
3) Loosen the fixing screw of the copy lamp unit wire. 
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 simul-
taneously, 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 mir-
ror unit positioning plate and the other side does not, the paral-
lelism 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 pul-
ley 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. 
9) Set the image distortion check chart on the document table, and
make a reduction copy (75%) on an A4 or 11
″  × 8 1/2″ paper
with the document cover open.

10) Check the horizontal image distortion.
If LL = LR, there is no horizontal distortion
11) If LL is not equal to LR, perform the following procedure.
Loosen the setscrew of the copy lamp unit/No.2/3 mirror unit
drive pulley in the front or the rear frame. 
12) Without moving the copy lamp unit/No.2/3 mirror unit drive pul-
ley shaft, manually turn the copy lamp unit/No.2/3 mirror unit
drive pulley whose setscrew was loosened, and adjust the
parallelism of copy lamp unit/No.2/3 mirror unit. 
13) Tighten the set screw of the copy lamp unit/No.2/3 mirror unit
drive pulley. 
14) Check the image distortion in the same manner as step 10).
Repeat procedures 11) to 14) until horizontal image distortion
is eliminated.
(2) Vertical image distortion adjustment
a. Summary
In this adjustment, the left and right balance is adjusted by changing
the left and right balance of the No. 2 scanner unit frame on the
front frame side.
b. Note
Horizontal image distortion adjustment
c. Cases when the adjustment is required
1) When the copy lamp unit/No.2/3 mirror unit drive section is dis-
assembled or its part is replaced. 
2) When the copy image is distorted as follows:
d. Necessary tools

Test chart for distortion adjustment (Make by yourself.)
Draw a rectangle on A4 or 8 1/2
″ × 11″ paper as shown below:
Be sure to make four right angles. 
e. Adjustment procedure
1) Set the test chart for image distortion adjustment on the docu-
ment glass, and make a normal copy on a paper of A4 or 8 1/2
× 11″.
2) Check image distortion in the right and the left sides.
If the both vertical lines are in parallel with each other, the right-
left distortion balance is proper. (However, there may be some
distortion.)
2)
If all the four angles are right angles, there in no distortion and
the following procedures are not required.
