1.2.3 When Nozzle Change cannot be performed automatically
When a nozzle change error has occurred, adjust the threshold by putting in and taking out a
nozzle from the station by hand.
1. Select Adjust Sensor from Menu.
Click the [025 ANC Manual] button on the main menu of the CalibSm and select Adjust Sensor
from Menu.
Figure 9
2. Store all the nozzles in the ANC.
3. Perform teaching for the detection level when the nozzle is in the station.
If an error occurred to the No.52 nozzle, click the [52] button on the T column on the right side of
the window.
The sensitivity (Threshold) when the nozzle is in the station is displayed in the First field.

4. Perform teaching for the detection level when the nozzles is out of the station.
Take out the nozzle from the No.52 station and click the [52] button on the right side of the
window.
The sensitivity (Threshold) when the nozzle is taken out of the station is displayed in the Second
field.
Also the value intermediate between the results of the first and the second round of measurement
is displayed in the Result field.
Figure 11
5. Check the measured result.
Repeat the measurement several times and make sure that there is enough difference
between the results of the first and the second round of measurement, and the difference
does not vary much.
Before shipment of the machine, the difference between the two measured results is set to
be approx. 800. However, if the difference is 400 or less even after cleaning the parts
related to nozzle detection, it is recommended to replace the ANC control board Assy.
Compare the Tol value (The current threshold) and the Result value (The threshold after
the measurement).
When there is not much difference between the Tol value and the Result value, save
the data.
If the difference is significant, identify the cause of it and take appropriate measures, and
perform the adjustment again.
6. Save the measured result.
When you need to save the measured result as the new threshold, click the [52] button on the T
column (Teach button).

7. Perform the adjustment for other nozzles.
If other sensors need to be adjusted, repeat the procedures from step 3 through step 6.
If other nozzles can be changed automatically, use the ANC Auto utility for the adjustment.
Click the [52] button.

2. Clean the parts of the ANC related to nozzle detection
If the nozzle storage part of the ANC gets dusty, the reaction of the sensor becomes unstable.
Make sure to clean the area regularly.
2.1 Clean the Acrylic board
1. Shut off the main air supply of the machine.
Turn the air pressure supply/shutoff switch to the Shutoff side in order to shut off the air supply
to the machine and release the residual pressure.
2. Close the ANC shutter by hand.
3. Remove the nozzle storage part from the ANC body.
Remove the six (6) fixing screws and remove the nozzle storage part from the ANC body.
Figure 13
4. Remove the dust on the surface of the acrylic board.
After removing the nozzle holder, if the acrylic board under the holder is dusty, clean it with soft
cloth.
5. Attach the nozzle storage part on the ANC body.
Clean the mounting surface of the nozzle storage part, and attach the nozzle storage part so that
the ANC shutter position matches the position of the cylinder for opening/closing the shutter.
The position is determined by the two (2) positioning pins, so the coordinate adjustment is not
required after attaching the nozzle storage part.
Caution:
If a chip or dust gets between the mounting surface and the nozzle storage part, the ANC coordinate
changes, and the nozzle change cannot be performed automatically. Make sure to clean the surface
beforehand.
