Check the maximum and minimum liquid amounts.
1. Press the [Auto Input Timer] button and enter the maximum value of the timer. If the maximum value
is unknown, set “60” (estimated maximum liquid amount), and press the [OK] button. The setting
value will be evenly allocated to each section.

2. Press the [Execute] button to measure each section. The paper feed dialog box appears. Check that
no dots remain and press the [OK] button.
3. On the [Monitor]-[Vision] screen, check the recognition results and press the [Yes] button while
saving the measurement data.
4. If there is any timer that could not recognize a dot or caused a dispensing error (for example, dots
are connected), enter the timer values manually and make measurement again. Then check the
minimum and maximum timer values.
Timer value input
Examples
Timers “7” and “60” caused
recognition error or dispensing error.
Enter timer “8” or more.
Enter timer “59” or less.

Set the timer values.
Enter the minimum and maximum timer values manually so that the liquid amount of each dot becomes
equal. The timer value closest to 20 should be set to “20”.
7
Save the measurement data.
1. The dialog box for paper feed appears. Check that no dots remain and press the [OK] button.
2. When the measurement is complete, the dialog box for saving data appears. Check the
measurement results and press the [Yes] button to save the data.
3. Repeat the measurement several times until the dispensed area of timer “20” becomes stable and
close to the standard area, and then save the data.

Press the [Close] button.
When the setting for all section is completed, press the [Close] button.

Enter the offset value in each section.
Enter the offset values so that the area at timer “20” matches the standard area. Open the [Machine]
- “Specification Information” - “Dispense Correction” screen, and set the correction type. Enter “0.1900”
for timer “20” and then enter the offset amounts for other sections.
(Example) If the standard area at timer “20” is “0.187”, then add 0.003 to that value to obtain “0.1900”
and also add “0.003” to the other areas.

3.1.7 Setting the calculation type
The dispensed area tends to get smaller when the liquid level in the syringe drops. Setting the calculation type
allows correcting to a more accurate dispensing area. There are two calculation types for making corrections:
proportion type and constant type. Make a graph by measuring the area of each dispensing amount with a
syringe having the liquid level from 10 to 50% and determine the calculation type. This section describes the
procedure for setting the calculation type using a Type 111 nozzle as an example.
1
Set up the head unit.
Prepare a target nozzle and syringe having a 10 to 50% liquid level and attach them to the head. If a
syringe is already attached in the previous section, then expel some liquid from the syringe until the
liquid level becomes 10 to 50%.
n
NOTE
The difference is easier to see when the liquid amount is small, making it easier to set the calculation type.
2
Bleed the nozzle air.
When setting the temperature, bleed the air after waiting until the target temperature is reached. For
the instructions on how to bleed the nozzle air, see “3.6 Bleeding the nozzle air” in Chapter 2.

Start the adjustment utility.
1. Press the [Utilities] button.
2. Select “Operator” and press the [OK] button.
3. Press the [Dispense Correction] button.
