MX-3640N ADJUSTMENTS AND SETTINGS 5 – 72
12-B
Adjust the sensitivity of the original size
sensor
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.

Touch panel coordinate setting
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.
* 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
In case of a n error, the display r eturns to the entry screen
again.

Fusing paper guide position
adjustment
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
* 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
* 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.
