[8] ADJUSTMENTS
Each adjustment item in the adjustment item list is indicated with its JOB number. Perform the adjustment procedures in the sequence of Job
numbers from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, however, the sequence from the smallest to the greatest JOB number must be
observed.
If the above precaution should be neglected, the adjustment would not complete normally or a trouble may occur.

Print off-center adjustment
1) Execute SIM.50-10 by the key operation of the machine. Then,
the displays shown on the right side appear.
2) The print off-center adjustment value can be set for each tray.
3) Press the [
3) Press the [
↓] key on the touch panel to select “G:50:LCC”.
4) Then, enter your desired adjustment value with the [10] key.
(Default: 50 Adjustment range: from 1 to 99)
* If the adjustment value is decreased by 1, the main scanning
* If the adjustment value is decreased by 1, the main scanning
print position is shifted to the front side by 0.1mm.
* If the adjustment value is increased by 1, the main scanning
print position is shifted to the rear side by 0.1mm.
5) When the [EXECUTE] button is pressed, the [EXECUTE] but-
ton is highlighted, currently set value is saved into the
EEPROM and the RAM, and printing for adjustment pattern
image is started. After printing is finished, the [EXECUTE] but-
ton returns to the normal display status.

satisfy the conditions shown below.
If condition of A - B = 0
±3.0mm is satisfied, no adjustment is
necessary.
If it does not satisfy the condition above, execute the proce-
dures shown below.

dures shown below.
7) Change the adjustment value. Repeat the steps from 4) to 6)
until the condition described in the step 6) is satisfied.
8) After the adjustment is finished, escape from the simulation
mode with the reset key.
