Loosen  the or iginal  cover  switch actuator   adjustment scr ew

and  slide the   actuator  position  so that t he  display OCSW  is

returned to the normal display when the height of the arm unit

top from the table glass is 20.2  0.25mm by slowly tilting the

document detection arm unit in the arrow direction and adjust. 

(If the ON timing of the original cover switch is shifted, the doc-

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  SIZE

PHOTO SENSOR LEVEL IS ADJUESTED" is displayed.

 

This adjustment must be performed in the following cases:
* 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 cr oss  mark  is p ressed  precisely,  a bu zzer  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 a n  error,  the  display r eturns  to  the  entry  screen

again.
Check  to confirm that ther e  is  no shif t  between  the  display

frame  and the  detection  position when the touch p anel  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 p aper,  change  the  position in the

arrow direction B.

MX-3640N  ADJUSTMENTS AND SETTINGS  5 – 73

 

Normally if the adjustment is executed by ADJ 4 (automatic adjust-

ment), there is no need to execute this adjustment.
Only when the manual adjustment is required, execute this adjust-

ment.
In other words, this manual adjustment is executed when a  satis-

factory result is not obt ained from the automatic adjustment (ADJ

4).

 

This adjustment must be performed in the following cases:
* 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 halftone is 240 

0.5mm.

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

6) Change the set value of set item A.

When the set value is changed by 1, the dimension is changed

by 0.1mm.
When the set value is increased, the  BK image magnification

ratio in the main scanning direction is increased. When the set

value  is  decreased,  the  BK  image  magnification ratio  in  the

main scanning direction is decreased.

Repeat procedures 2) - 6) until a satisfactory result is obtained.

 

This adjustment must be performed in the following cases:
* When the LSU is replaced or removed.
* When a paper tray is replaced.
* When the paper tray section is disassembled.
* When the manual feed tray is replaced.
* When the manual feed tray is disassembled.
* When the duplex mode paper transport section is disassembled.
* When the registration roller section is disassembled.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.

Before execution  of  this adjustment,  be sure to  execute the  print

image  magnification r atio  adjustment  (ADJ  15A) ( main  scanning

direction) (print engine) (manual adjustment).
