b. Adjustment procedures
1)

Enter the SIM67-54 mode.

2)

Press [EXECUTE] key. (A3 or 11" x 17" paper is automatically
selected.)
The color patch image (adjustment pattern) is printed out.

3)

Set the color patch image (adjustment pattern) printed in the
procedure 2) on the document table so that the thin lines on
the printed color patch image (adjustment pattern) are on the
left side. Place 5 sheets of white paper on the printed color
patch image (adjustment pattern).

4)

Press [EXECUTE] key.
The color balance adjustment is automatically performed.
The adjustment pattern is printed out. Check it for any abnor-
mality.

5)

Press [OK] key.
The list of the adjustment items (for each dither) is displayed.

6)

Select an adjustment item (for each dither).

7)

Press [EXECUTE] key. (A3 or 11" x 17" paper is automatically
selected.)
The color patch image (adjustment pattern) is printed out.

8)

Set the color patch image (adjustment pattern) printed in the
procedure 7) on the document table so that the thin lines on
the printed color patch image (adjustment pattern) are on the
left side. Place 5 sheets of white paper on the printed color
patch image (adjustment pattern).

9)

Press [EXECUTE] key.
The color balance adjustment is automatically performed, and
the color balance check patch image is printed out.

10) When [OK] key is pressed, the adjustment result is registered

and the adjustment mode is terminated. When [EXECUTE]
key is pressed, the adjustment result is registered and the
screen is shifted to the other item (Mode/Image) select menu.
To execute the adjustment of the other item (Mode/Image),
press [EXECUTE] key.
After completion of all the adjustments of the items (Mode/
Image), press [OK] key, and the adjustment results are regis-
tered.

11) Make a print, and check the print image quality.

NOTE: Use SIM67-52 to reset the adjustment values to the default

values.

 

Normally there is no need to perform this adjustment. In the follow-
ing cases, perform this adjustment.
* When a paper jam occurs in the fusing section.
* When wrinkles are made on paper in the fusing section.
* When an image deflection or an image blur is generated in the

paper rear edge section.

1)

Remove the fusing paper guide fixing screws which are on two
position in the front/rear frame direction.

2)

Insert the removed screws of the fusing paper guide into the
screw hole in the paper guide long hole section.
Loosely tighten the screws so that the paper guide can be
moved in the directions of A and B.

3)

Use the fusing paper guide position scale as the reference to
shift the paper guide in the arrow direction A or B.

The standard fixing position is the center of the marking scale.
Change the position according to the situation.
* When wrinkles are generated on paper, change the position

in the arrow direction B.

* When an image deflection or an image blur is generated in

the paper rear edge section, change the position in the
arrow direction A.
Normally, the hole on the fusing paper guide standard fixing
position is used to fix the fusing paper guide.

MX-4101N  ADJUSTMENTS  5 – 98

 

This adjustment is needed in the following situations:
* When the original size sensor section has been disassembled.
* When the original size sensor section has been replaced.
* When U2 trouble has occurred.
* When the scanner control PWB is replaced.
* When the EEPROM on the scanner control PWB is replaced.

 

1)

Go through the modes specified in Simulation 41-1.

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 SIM41-2 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
SENSOR LEVEL IS ADJUESTED" is displayed.

 

This adjustment is needed in the following situations:
* The manual paper feed tray section has been disassembled.
* The manual paper feed tray unit has been replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.

6)

Open the RSPF/DSPF paper feed guide to the width for the
A5R size.

7)

Press [EXECUTE] key.
The A5R width detection level is recognized. 

8)

Open the RSPF/DSPF paper feed guide to the minimum width
position.

9)

Press [EXECUTE] key.
The minimum width detection level is recognized.
* When each of the above operations has been completed,

the "COMPLETE" message appears; when any of the oper-
ations has failed, the "ERROR" message appears.

 

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)

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).
