• 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.
• Substitute the "O – L" value (variation in the distance be-
tween the original and the lens) on the lens value label at-
tached to position B shown in the figure below into the follow-
ing formula, and input the obtained value.
50 – {(O – L value) × 5} = Correction reference value
When the lens value is +1.2;
50 – (1.2 × 5) = 44 (Correction reference value = input
value)
Be sure to check that the magnification ratio cam is at the home
position as shown in the figure below.
