MX-DEX1/DEX2  ADJUSTMENT  8 – 1
Service Manual      
 
[8] ADJUSTMENT
Each adjustment item in the adjustment item list is indicated with its
JOB number.  The adjustment procedures should be performed in
the ascending order of Job numbers.
However, you do not have to always perform all the adjustment
items.  Perform only the necessary adjustments according to the
actual conditions. 
Skip any unnecessary adjustment items, and perform the next nec-
essary item.  Even with some items skipped, the adjustment proce-
dures should be performed in the ascending order of Job numbers.
Failure to perform the adjustment items in the correct order may
result in adjustment errors or some other problems. 
To start a simulation: 
1)
Press the [COPY MODE] key to turn on Copy mode. 
2)
Press the following keys exactly in this sequence: 
[P] (Program), [*] (asterisk),  [C] (Clear), [*]. 
3)
This displays the Simulation Main Number Entry screen (which
means that the system is waiting for user input).

1
Print off-center adjustment
1)
Run SIM50-10 using the keypad on the main unit.  
The following screen appears: 
2)
This screen allows you to configure the print off-center adjust-
ment value for each paper feed tray.
<Detailed Description>
3)
On the touch panel, press [
↓] to select "E: 50 : CS3" or "F:
50 : CS4." 
4)
Enter the desired adjustment value through the numeric key-
pad. 
(This value, which defaults to 50, can be adjusted within the
range of 1 to 99).
• Reducing the adjustment value by 1 causes the main scan/
print position to shift by 0.1 mm toward the rear. 
• Increasing the adjustment value by 1 causes the main scan/
print position to shift by 0.1 mm toward the front. 
5)
After entering the adjustment value, press the [EXECUTE] key
on the touch panel to start printing and save the setting.
6)
Check that the adjustment pattern image is printed in the cor-
rect position.
Measure the dimensions of the void areas on the front- and
rear-frame sides of the adjustment pattern image, and make
sure that the following conditions are met: 
No adjustment is needed if A - B = 0 
±3.0 mm.
If the above condition is not met, do the following:
7)
Change the adjustment value. 
(Enter a new adjustment value and press the [OK] key).
Changing the adjustment value by 1 shifts the position by
approximately 0.1 mm. 
Repeat steps 4) to 6) until the condition shown in step 6) is sat-
isfied.
8)
After you have completed the adjustment, exit from Simulation
mode by pressing the [CA] key.
 
2
Resist amount adjustment
1)
Run SIM51-2 using the keypad on the main unit. 
The following screen appears. 
This screen allows you to configure the resist amount adjust-
ment value for each paper feed tray. 
<Valid Range and Default Value of Each Setting>
2)
On the touch panel, press the [
↓] to select "O: 50 : DESK (S)"
or "P: 50 : DESK (L)." 
3)
Enter the desired adjustment value through the numeric key-
pad. 
(This value, which defaults to 50, can be adjusted within the
range of 1 to 99).
Increasing the adjustment value by 1 causes the resist amount
to increase by 1 msec. 
4)
After entering the adjustment value, press the [OK] key on the
touch panel  to save the setting. 
5)
After you have completed the adjustment, exit from Simulation
mode by pressing the [CA] key.

Print leading edge adjustment
1)
Run SIM50-5 using the keypad on the main unit. 
The following screen appears. 
2)
Press the [EXECUTE] button to highlight it. 
The main unit starts printing an adjustment pattern image
using the currently configured values.  
Upon completion, the [EXECUTE] button becomes unhigh-
lighted. 
* To save the currently configured settings into the EEPROM
and RAM, press any of the following: [
↑] or [↓] button, [OK]
button, [EXECUTE] button, [Color] or [Monochrome] key.
* At any time during printing, you can suspend the test print by
pressing any of the following: the [C] key, [CA] key, [SYS-
TEM SETTING] key, and [EXECUTE] button. 
* After being stopped from printing, the main unit resumes the
self-print test when it becomes ready. 
3)
Select "E: PAPER" and choose the desired paper feed location
(in this example, CS3 and CS4). 
4)
Check that the adjustment pattern image is printed in the cor-
rect position. Measure the dimensions of the void areas on the
left- and right-frame sides of the adjustment pattern image,
and make sure that the following conditions are met: A=4.0
±2.0 mm B=4.0 ±2.0 mm. If this conditions are met, no adjust-
ment is needed. 
If the above conditions are not satisfied, proceed to steps 5)
and 6).
5)
Change the adjustment values for adjustment items A (DEN-
C) and B (DEN-B). 
* Reducing the adjustment value for item A (DEN-C) by 1
causes the print start point relative to the paper transport
direction to shift toward the paper leading edge by 0.1 mm. 
* Reducing the adjustment value for item B (DEN-B) by 1
causes the sub-scan-directional print range, relative to the
paper transport direction, to decrease by 0.1 mm. 
6)
Repeat steps 2) to 5) until the conditions shown in step 4) are
satisfied.

This adjustment value is intended to adjust the print leading edge for the printer.  
Reducing the adjustment value for item A (DEN-C) by 1 causes the print start point 
relative to the paper transport direction to shift toward the leading edge by 0.1 mm.

This adjust value controls how much void will be created at the trailing edge of the 
paper.  Reducing the adjustment value for item B (DEN-B) by 1 causes the sub-scan-
directional print range, relative to the paper transport direction, to decrease by 0.1 
mm.
