MX-M260/M310/M260N/M310N ADJUSTMENTS 5 - 7
4) Move the mirror base B rail position up and down (in the arrow
direction) to adjust.
<Adjustment specification>
La = Lb, Lc = Ld
5) After completion of adjustment, manually turn the mirror base drive
pulley, scan the mirror base A and mirror base B fully, and check
that the mirror bases are not in contact with each other.
∗ If the mirror base rail is moved extremely, the mirror base may be in
contact with the frame or the original glass. Be careful to avoid this.
(9) Main scanning direction (FR direction) magnification
ratio adjustment (SIM 48-1)
Note: Before performing this adjustment, be sure to check that the
CCD unit is properly installed.
1) Put a scale on the original table as shown below.
2) Execute SIM 48-1.
3) After warm-up, shading is performed and the current set value of
the main scanning direction magnification ratio is displayed on the
display section in 2 digits.
4) Manual correction mode (SIM48-1-1)
Enter the set value and press the start key.
The correction value is stored and a copy is made.
<Adjustment specification>
Note: A judgment must be made with 200mm width, and must not be
made with 100mm width.
(10) Sub scanning direction (scanning direction)
magnification ratio adjustment
(SIM 48-1-2, SIM 48-1-3)
a. OC mode in copying
Note: Execute the procedure after completion of SIM 48-1-1.
1) Put a scale on the original table as shown below, and make a nor-
mal (100%) copy.
2) Compare the scale image and the actual scale.
If necessary, perform the following adjustment procedures.
3) Execute SIM 48-1-2.
4) Enter the set value and press the start key.
The set value is stored and a copy is made.
<Adjustment specification>
b. RSPF mode in copying
Note: Before performing this adjustment, be sure to check that the
CCD unit is properly installed and that OC mode adjustment in
copying has been completed.
1) Put a scale on the original table as shown below, and make a nor-
mal (100%) copy to make a test chart.
Note: Since the printed copy is used as a test chart, put the scale in
parallel with the front side edge of the glass.
2) Set the test chart on the RSPF and make a normal (100%) copy.
3) Compare the scale image and the actual image.
If necessary, perform the following adjustment procedures.
4) Execute SIM 48-1-3.
5) After warm-up, shading is performed.
The current front surface sub scanning direction magnification ratio
correction value is displayed in two digits on the display section.
• When La > Lb
Shift the mirror base B rail upward by the half of the difference of
La–Lb.
• When La < Lb
Shift the mirror base B rail downward by the half of the difference
of Lb–La.
Example: When La = 12mm and Lb = 9mm, shift the mirror base
B rail upward by 1.5mm.
• When Lc >Ld
Shift the mirror base B rail downward by the half of the difference
of Lc–Ld.
• When Lc < Ld
When Lc < Ld, move the mirror base B on the paper feed side
upward.
∗ When moving the mirror base rail, hold the mirror base rail with
your hand.
