AR-LC6  ADJUSTMENT  6 - 1

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.

1) Set the print off-center adjustment mode of SIM 50-10 by the key

operation of the machine. (Press the keys as shown below to enter
SIM 50-10.)

2) In SIM 50-10, the display is shown as follows. The print off-center

adjustment value can be set for each paper feed tray.

3) Select "0: TRAY SELECT" and press START key. 

The display is shown as follows. Select "6: LCC" as the paper feed
tray, and press START key.

4) The display is shown as follows again. Select "8: LCC" and press

START key.

5) Then enter the adjustment value with 10-key.

(Default: 50, Adjustment range: 0 – 99)

• When the adjustment value is decreased by 1, the image is

shifted to the rear side by 0.1mm.

• When the adjustment value is increased by 1, the image is

shifted to the front side by 0.1mm.

6) Enter the adjustment value and press START key, and printing is

started and the set value is stored.

7) Check the printed self-print result, and repeat procedures 5) – 6)

until the value is in the range of 0 ± 3mm.

When the value is in the above range, press CA key to terminate
the simulation.
