(4) Calculate the copy magnification ratio.
Copy magnification ratio =
Copy image size
Original size × 100%
(5) Check that the obtained copy magnification ratio is within the
specified range (100 ± 0.8%). If it is within the specified range,
go to procedure (7). If not, execute simulation 48-1.
• Perform the following key operation.
"A" is displayed on the third digit of the copy quantity dis-
play, and the previously set value or 50 is displayed on the
second and the first digits. (Refer to "D-1. Lens reference
position adjustment.")
(6) Perform the magnification ratio adjustment according to the
flowchart below.
(7) Copy the scale at 200%.
(8) Check that the copy magnification ratio is within the specified
range (100 ±0.9%). If it is within the specified range, go to
procedure (9). If not, enter % key in simulation 48-1 as fol-
lows:
• Perform the following key operation.
"B" is displayed on the third digit of the copy quantity dis-
play, and the previously set value of 50 is displayed on the
second and the first digits.
(9) Adjust the copy magnification ratio according to the flowchart
shown in (6).
(10) Make a copy at 50%.
(11) Check that the copy magnification ratio is within the specified
range (100 ±0.9%). If it is in the specified range, the vertical
copy magnification ratio is completed. If not, enter [%] in
simulation 48-1 as follows:
• Perform the following key operation.
"C" is displayed on the third digit of the copy quantity dis-
play, and the previously set value or 50 is displayed on the
second and the first digits.
(12) Adjust the copy magnification ratio according to the flowchart
shown in (6).

Normal copy ratio focus adjustment
(1) Check the "O.L value" on the lens value label of the lens unit,
and fit the reference position of No. 4/5 mirror. (Use the No.
4/5 mirror adjustment screw for positioning. Loosen screw A at
this time.)
