MX-LCX3N  ADJUSTMENTS  8 – 1

MX-LCX3N

Service Manual

 

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 an error may occur.

 

1) Execute SIM.50-10. The displays shown at the right will

appear.

2) The print off-center adjustment value can be set for each tray.
3) Press the [

↓] key on the touch panel to select “H: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

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 the adjustment pat-
tern image is started. After printing is finished, the [EXECUTE]
button returns to the normal display status.

6) Check the adjustment pattern image position.

Measure the dimensions of the void area in the adjustment
pattern front and rear frame directions, and ensure that they
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.

7) Change the adjustment value. Repeat the steps from 4 thru 6

until the condition described in the step 6) is satisfied.

8) After the adjustment is finished, escape from the simulation

mode with the CA key.

* The screen above is intended for the model of MX-5500N series.

In the installation on other models, standard values are different.
