Test start
Print the patterns from the test start voltage to the test finish volt-
age (both set in the step 9) in increments of set step value.
* Numerical values indicate offset values for the head reference
voltage.

8. Select the nozzle row (color) to be adjusted.
Select target nozzle
9. Enter the offset voltage used when printing a pattern for adjust-
Enter test start voltage
e.g.: 0.0V
Enter test finish voltage
e.g.: 2.0V
Enter step value from test
start to test finish
e.g.: 0.2V
10. Press [ENTER] key to start printing.
11. Find the optimum offset value.
Test end
12. Set the offset voltage.

ment.
(The pattern will look like the image shown in the step 11
below.)
1),Set the offset voltage for printing the first pattern.
(-3.0 to +3.0V, increments of 0.1V).
2),Set the offset voltage for printing the last pattern.
(-3.0 to +3.0V, increments of 0.1V).
3),Set the voltage added at every step from the above 1) to 2).
(0.1 to +1.0V, increments of 0.1V)
The entered values are reflected to the reference volt-
age of the head.
(A preset offset value will be ignored.)
Enlarge the pattern and find the offset value which presents the
acceptable (within the specified range), smallest deviation in Y
direction.
The acceptable range of deviation is given in the step 5.
Enter the value considered optimum in the step 11.
