8) Open the manual paper feed guide to the minimum width posi-

tion.

9) Press [EXECUTE] key.

[EXECUTE] key is highlighted. Then it returns to the normal
display.
The minimum width position detection level of the manual
paper feed guide is recognized.

If the above operation is not completed normally, "ERROR" is dis-
played.
When the operation is completed normally, the above data are
saved to the memory and "COMPLETE" is displayed.

 

This adjustment must be performed in the following cases:
• The DSPF/RSPF paper feed tray section has been disassem-

bled.

• The DSPF/RSPF paper feed tray unit has been replaced.
• When a U2 trouble occurs.
• The scanner PWB has been replaced.
• The EEPROM on the scanner PWB has been replaced.
1) Enter the SIM 53-6 mode.

2)

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

3)

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

4)

Open the DSPF/RSPF paper feed guide to the width for the
A4R size.

5)

Press [EXECUTE] key.
The A4R width detection level is recognized.

6)

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

MX-4070V  ADJUSTMENTS AND SETTINGS  5 – 65

 

This adjustment must be performed in the following cases:
• The operation panel has been replaced.
• U2 trouble has occurred.
• The SCN MFP PWB has been replaced.
• The EEPROM on the SCN MFP 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).

 

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) Loosen the fusing paper guide fixing screws on the two posi-

tions in the front/rear frame direction.

2) 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 at two scales in direction B from
the marking scale center. However, the position may be varied
depending on the situation.

* When a wrinkle is made on paper, change the position in the

error direction A.

* When an image deflection or unclear image is generated in the

lead edge area of paper, change the position in the arrow direc-
tion B.
