MX-3100N  ADJUSTMENTS  6 – 84

(Method 2)
Use SIM67-25 to print the color balance adjustment sheet and
compare the black patch color balance of each process (CMY)
with the black patch. This procedure allows checking the color
balance adjustment result correctly.

*1: In the case of the GDI printer, this section are not printed.
If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color table
in an actual printer mode. (When the color balance target is
DEF 1.)
If a satisfactory result on the print color balance and the den-
sity is not obtained with the automatic adjustment, execute the
manual adjustment (SIM 67-25) (ADJ 21B).

 

This adjustment is needed in the following situations:
* When the fusing section is disassembled.
* When a paper jam occurs in the fusing section.
* When a wrinkle is made on paper in the fusing section.
* When an image deflection or image blur occurs in the paper rear

edge section.

1)

Loosen the fixing screw C.

2)

Shift the fusing paper guide in the arrow direction A or B (up
and down direction).

The standard fixing position is the center of the marking scale.
Change the position depending on the situation.
* When a wrinkle is formed on paper, change the position

upward (in the arrow direction A).

* When an image deflection or image blur occurs in the paper

rear edge section, shift the position downward (in the arrow
direction A).

 

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.

MX-3100N  ADJUSTMENTS  6 – 85

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.

adjustment, the set value is saved to EEPROM and RAM
and the display is shifted to the tray volume A4R size adjust-
ment value start screen. (Each set value is saved to
EEPROM and RAM at each setting.)

3)

Set the tray document guide to A4R width position and press
[EXECUTE] button. The pressed button is highlighted and the
tray A4R size adjustment is started.

4)

Adjust the tray volume A5R size and the tray size volume min-
imum value according to the above procedures.

5)

Completion of the adjustment, "COMPLETE" is displayed. If
the adjustment is not completed normally for any reason,
"ERROR" is displayed. In that case, the adjustment must be
executed again.

<Adjustment item and content>

When one of 1-4 in the above table is selected, the guide plate is
shifted to each position of the four widths of the guide plate shown
in the table below. The value of the document width sensor
(RSPF_WIDTH) A/D value is saved to EEPROM.
<Guide plate positions and widths on the mechanism and A/D val-

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)

Enter the SIM 65-1 mode.

2)
