[7] 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).

ADJ 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-

<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.
 
ADJ 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.

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
