MX-7580N  2 – 19

1)

There are 12 void areas.

2)

The resolution of 4.0 (5 points) can be seen.

3)

The density difference between the F and the R sides is not so
great.

4)

There are no white and black streaks.

5)

Solid density is not so light.

6)

The black low-density gradation is copied slightly.

Solid density is not so light

Execute SIM 64-5 to print the print test pattern.

Set each set value to the default and press [EXECUTE] key. The
print test pattern is printed.

The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed. The density level of each color must be almost at the
same level.

* There must be a tray with A4 (LT) paper in it.

1)

Enter the Sim. 50-10 mode.

2)

Select a paper feed source “2“ (CS1).

3)

Set A4 (11 X 8.5) paper on the CS1 paper feed tray.

4)

Check to confirm that the inside dimension of the printed half-
tone pattern is 240

0.5mm.

If the above condition is not satisfied, follow and repeat the
procedures of ADJ3A(Service manual) until a satisfactory
result is obtained. 

5)

Measure the void area size of the adjustment pattern in the
front/rear frame direction (F side void amount) and that in the
transport direction (Lead edge void amount).

Check to confirm that all the following conditions are satisfied.

(Example) Lead edge void amount (Adjustment value: SUB-**)

F side void amount (Adjustment value: MAIN-**)

(1) Measure by visual inspection.

Measurement result: 4.5mm

(2) Calculate the shift amount.

The target value is the specification value (center value) of
4mm.

* For the F side void amount, the target is 2mm.
[4 – 4.5 = -0.5 (mm)]

(3) Calculate the adjustment value.

Subtract 5 from the shift amount of -0.5mm.

* For the shift amount of 0.1mm, the adjustment value is

varied by 1.

When the current value is 50:

[50 – 5 = 45]

(4) Enter the adjustment value for SUB-CS.

Enter the [45].

6)

Enter MAIN-CS1 (F side void) and SUB-CS1 (Lead edge void),
and press OK button.

Enter the calculated adjustment values for the shift amount to
MAIN-CS1/SUB-CS, and press OK button. (The cursor can be
used instead of the button.)

7)

After entering the adjustment values, print again and check to
confirm that the avoid amounts are adjusted to the target
range.

Make a copy in the original table mode and in the DSPF mode.
Check to confirm that the image loss and the void area are in the
range shown below.

Lead edge void area

4.0±1.0mm or less

Rear edge void area

From 2.0mm to 5.0mm

Lead/Rear edge total void area

8.0mm or less

FRONT/REAR edge total void area

4.0mm ±2.0mm or less

• Lead edge void amount 
   (4.0mm terget)

Measure at the center of 

paper. 

Adjustment value
J : SUB-**

Print

lead edge

Main scanning magnification ratio (240    0.5mm)
Measure the dimension near the inner frame line 
and the paper lead edge in parallel with the line.
    Adjustment value   A : BK-MAG

• F side void amount (2.0mm terget)
  Measure at a position near the 

paper lead edge. 

      Adjustment value 
      C : MAIN-**
