MX-M200D ADJUSTMENT 6-9

Note:Before performing this adjustment, be sure to check that the paper 

off center is properly adjusted. 

1) Make a test chart for the center position adjustment and set it on the 

SPF. 

Draw a line on a paper in the scanning direction. 
2) Make a normal copy from the bypass tray, and compare the copy and 

the original test chart.

 

If necessary, perform the following adjustment procedures. 

3) Execute SIM 50-12. 
4) After warm-up, shading is performed and the current set value of the 

off center adjustment at each paper feed port is displayed on the 
display section in 2 digits. 

5) Enter the set value and press the [START] key. 

 

The set value is stored and a copy is made. 

 

1) Fully open the SPF.
2) Execute SIM 63-7.

 

If the value is 93 - 229, it is displayed on the display and written into 
the EEPROM. 

 

If the value is 0 - 92 or 230 - 999, it is displayed on the display but not 
written into the EEPROM.

 

If the value is 1000 or above, “--” is displayed on the display and it is 
not written into the EEPROM.

•When the display is 0:
Check that the SPF is open.
Check that the lamp is ON.(If the lamp is OFF,check the MCU 
connector.)
Check that the CCD harness is properly inserted into the MCU 
connector.
•When the display is 281 or above:
1) Remove the table glass.
2) Remove the dark box.
3) Slide the lens unit toward the front side and attach it,then execute 

SIM.

•When the display is 143 or below:
1) Remove the table glass.
2) Remove the dark box.
3) Slide the lens unit toward the rear side and attach it,then execute 

SIM.

*

When the lens unit is moved,execute the OC main scanning 
magnification ratio auto adjustment,SIM 48-1-1,SIM48-3 and the PF 
original off-center adjustment.

*

This adjustment is basically O.K.with SIM 63-7.

1)Set a test chart (UKOG-0162FCZZ) on the OC table as shown below.

2) Put several sheets of A3 or 11" x 17" white paper on the test chart. 
3) Execute SIM 46-1.
4) After warm-up, shading is performed and the current set value of the 

density level is displayed on the display section in 2 digits. 

 

For mode selection, use the AUTO/TEXT/PHOTO key. 

5) Change the set value with the numeric keys to adjust the copy image 

density.

6) Make a copy and check that the specification below is satisfied.

When the clear all key is pressed, the simulation mode is cancelled.
When the interruption key is pressed, the process is interrupted and the 
screen returns to the sub code entering display.
* After canceling the simulation mode, be sure to turn OFF/ON the 

power and check the operation.

Note: If the machine is terminated by a jam error or paper empty during 

copying in the adjustment by the simulation, recopying is required.

Note:The values in the simulation columns are not default values but

Used to check the operations of the scanner unit and its control circuit. 
Enter the number of times and the magnification ratio, and press [OK] key to operate the scanner unit. The 
speed is variable according to the specified magnification ratio. The number of scanning can be specified by 
entering a value to the right lower section of the LCD.
•Setting range of magnification ratio: 25%-400%
•Setting range of the number of scanning: 0-999 (When 0 is set, it means unlimited. )

Used to display the status (ON/OFF) of the mirror HP sensor on the LCD during scanning. (Highlighted at 
ON)
"EXEC" is displayed to indicate execution is in process. The scan counter is displayed above "EXEC." This 
counter is counted up even in simulation.
 The copy lamp is lighted during scanning.

[CA] key: Exits the simulation mode.
[INTERRUPT] key: Returns to the sub code input window.
[C] key: Input value clear
Numeric keys: Input of the number of scanning
