1)

Enter the SIM 41-1 mode.

Loosen the original cover switch actuator adjustment screw
and slide the actuator position so that the display OCSW is
returned to the normal display when the height of the arm unit
top from the table glass is 32 

 0.5mm by slowly tilting the doc-

ument detection arm unit in the arrow direction and adjust. 
(If the ON timing of the original cover switch is shifted, the doc-
ument detection function may malfunction.)

 

1)

Enter the SIM 41-2 mode.

2)

Execute the sensor adjustment without document.
With the document cover open, without placing a document on
the table glass, press [EXECUTE] key.

3)

Place A3 (11" x 17") paper on the document table and press
[EXECUTE] key.
If the adjustment is completed normally, "DOCUMENT PHOTO

MX-M503N  ADJUSTMENTS AND SETTINGS  4 – 52

 

This adjustment is needed in the following situations:
* The operation panel has been replaced.
* U2 trouble has occurred.
* The scanner control PWB has been replaced.
* The EEPROM on the scanner control PWB has been replaced.
1)

Enter the SIM 65-1 mode.

2)

Precisely press the cross mark points (4 positions).
When the cross mark is pressed precisely, a buzzer sounds
and the display is reversed. When all the four points are
pressed and the touch panel adjustment is completed, the dis-
play returns to the simulation sub number entry screen.
In case of an error, the display returns to the entry screen
again.
Check to confirm that there is no shift between the display
frame and the detection position when the touch panel is
pressed.
* When pressing the touch panel, never use a sharp tip (such

as a needle or a pin).

 

The following adjustment items can be executed automatically with
SIM 50-28. It takes less time to use this adjustment than to use the
following manual adjustments.
* ADJ 3B Print engine image magnification ratio adjustment 

(Main scanning direction)

* ADJ 3C Print engine print area (void area) adjustment
* ADJ 3D Print engine image off-center adjustment
* ADJ 7 Scan image magnification ratio adjustment 

(Manual adjustment)

* ADJ 10 Copy image position, image loss, and void area adjust-

ment (Manual adjustment)
