2) Set the copy magnification ratio to 100%.

3) Make a copy on A4 or 8

⁄

″ × 11″ paper.

4) Measure the length of the copied scale image.

5) Calculate the main scanning direction magnification ratio.

6) Check that the copy magnification ratio is within the

specified range. If it is not within the specified range, per-

form the following procedures.

7) Execute SIM 48-1 to select the main scanning direction

copy magnification ratio adjustment mode.

To select the adjustment mode, use the copy mode

select key.

In the case of the automatic adjustment, when the PRINT

switch is pressed, the mirror base unit moves to the white

plate for shading to scan the width of the reference line, cal-

culating the correction value and displaying and storing this

value.

After execution of the automatic adjustment, go out from the

simulation mode and make a copy to check the magnifica-

tion ratio.

If the magnification ratio is not in the specified range (100

±1.0%), manually adjust as follows.

8) Set the adjustment mode to Manual with the copy mode

select key.

9) Enter the new set value of main scanning direction copy

magnification ratio with the copy quantity set key, and

press the COPY button.

10) Change the set value and repeat the adjustment until

the ratio is within the speoified range.

When the set value is changed by 1, the magnification

ration is changed by 0.1%.

I. Note

Before performing this adjustment, the following adjustments

must have been completed. If not, this adjustment cannot be

performed properly.

● Image distortion adjustment

● Must be installed to the lens unit reference position.

II. Cases when the adjustment is required

1) When the lens and the mirror unit are disassembled or

the part is replaced.

2) When the scanner unit drive section is disassembled or

the part is replaced.

3) When the main PWB is replaced.

4) When the EEPROM in the main PWB is replaced.

5) When “U2” trouble occurs.

6) When the copy image distortion adjustment is performed.

III. Necessary tools

● Screwdriver (+)

● Scale

IV. Adjustment procedure

1) Set the scale on the document table as shown below.

(Use a long scale for precise adjustment.)

2) Set the copy magnification ratio to 100%.

3) Make a copy on A4 or 8

⁄

″ × 11″ paper.
