MX-M565N  ADJUSTMENTS AND SETTINGS  4 – 8

Compare the right angle of vertical side and the horizontal side
of the rectangle print pattern with the right angle of A3 or 11" x
8.5" paper for judgment of good or no good.

(NOTE)

In the case of Method 2, the right angle of paper to be used
may not be exact. Be sure to check the right angle of paper to
be used in advance.

a) Measure the length of the diagonal lines of the rectangle
print pattern.

b) Calculate the difference between the measured lengths C
and D of the diagonal lines.

c) Check to insure that the difference between C and D is in
the following range. C - D = ±0.8mm

If the difference between C and D is in the above range, there
is no need to adjust.

a) Fit the side of A3 or 11" x 17" paper to the long side of the
rectangle print pattern.

b) Measure the shift distance between vertical side of paper
and side of the rectangle print pattern.

If the above distance is 0.5mm or less, there is no need to
adjust.

If not, execute the following procedures.

6)

Open the front cover.

7)

Adjust the print image distortion adjustment screw to set the
print image distortion to the minimum.

8)

Execute procedures 4) and 5).

(Repeat procedures 4), 5) and 7) until a satisfactory result is
obtained.)

 

This adjustment is needed in the following situations:

* When the LSU (writing) unit is replaced.

* U2 trouble has occurred.

* The PCU PWB has been replaced.

* The EEPROM of the PCU PWB has been replaced.

1)

Enter the SIM 50-10 mode.

2)

Set A4 (11" x 8.5") paper in the paper feed tray.

3)

Select the paper feed tray set in procedure 2) with the scroll
key.

4)

Press [EXECUTE] key.

The check pattern is printed out.

5)

Check that the inside dimension of the printed half tone is 240

 0.5mm.

If the above requirement is not met, do the following steps.
