1.2.2 Cleaning the nozzle tip
A little dirt at the nozzle tip can be cleaned with the "Nozzle tip cleaning tape" that comes with the machine.
If cleaning the nozzle with an ultrasonic cleaner (option) and then cleaning with the nozzle tip cleaning tape,
the nozzle tip can be cleaned effectively.
The following describes the cleaning procedure of the spring-action nozzle tip with an ultrasonic cleaner and
the nozzle tip cleaning tape.
c
CAUTION
When cleaning the nozzle tip, use YAMAHA recommended cleaning tape (TAPE,CLEANER:KGT-M8895-00X) only. If
using other tape, the adhesive surface may adhere to the nozzle and may cause the mounting failure.
n
NOTE
See the Service Information that comes with the tape for how to use the cleaning tape.

Remove nozzles.
1. Press the emergency stop button and
then open the machine safety cover.
2. Remove nozzles from the head. If the
machine is equipped with the nozzle
station, press the [Nozzle Stn Shutter]
button to open the nozzle station shutter
and remove nozzles.

Clean nozzles with an ultrasonic
cleaner.
1. Put nozzles into a container (such as
beaker) in an ultrasonic cleaner.
2. Pour IPA in a container until nozzles are
dipped.
3. Pour water in an ultrasonic cleaner.
4. Clean nozzles with an ultrasonic cleaner
for about 10 minutes.

NOTE
When cleaning a nozzle with an O-ring such as Type
304A or Type 307A nozzle using an ultrasonic cleaner,
remove an O-ring and clean a nozzle itself only.

Blow nozzles.
1.
Take nozzles out from an ultrasonic cleaner
.
2. Blow entire nozzle to remove IPA.
Intensively blow the slide section and the
air path.

CAUTION
If turning or tilting a nozzle while pushing it against the
tape, the adhesive surface may stick to the nozzle.

1.3 Checking the conveyor sensor condition and operation
This machine uses a transmission type fiber sensor as the conveyor sensor.
As the conveyor width changes, the distance between the light emitting and light receiving sensors also
changes. Accordingly, the light receiving status of the sensor may change.
Therefore, a conveyor sensor tuning function is provided on this machine that stores the sensor light receiving
status after the conveyor rail width has been changed and automatically rewrites the sensor threshold value.
By changing the conveyor rail width periodically, you can check that the conveyor sensors and conveyor sensor
tuning operate correctly.

1
Open the [Unit] – [Conveyor]
screen.
2
Press the [Width] button to change
the conveyor width.
In the "Conveyor Width" screen that
appears, enter a conveyor width and press
[OK] button.
The conveyor is changed to the width that
was just entered.
3
Check whether an error has
occurred.
The conveyor sensor is operating properly
unless an error message appears when the
conveyor width is changed. No further
check is necessary.
If an error occurred, perform "Conveyor
sensor tuning" from Step 4.

Perform the conveyor sensor
tuning.
1. Open the [Unit] – [I/O] screen.
2. From the "Output" drop-down list, select
"CONVEYOR".
3. Select "CONV SENSOR TUNING" (T01000E1)
in the output I/O list.

NOTE
In dual-lane machines, "T01000E1" corresponds to Lane
1, and "T01000E3" to Lane 2.
4. Press the [ON/OFF] button to switch the I/
O status from "0" (OFF)
→
"1" (ON)
→
"0"
(OFF) to perform auto tuning.
