6.2 Checking the nozzle station sensor condition (option)
When the machine is equipped with a nozzle station (option), check the nozzle station sensor condition.

CAUTION
If a nozzle station sensor fails to detect a nozzle, the nozzle change cannot be performed correctly and the machine
operation may be interrupted due to a nozzle detection error.
1
Open the nozzle station shutter.
1. Open the [Unit]-[Head] screen.
2. Press the [Nozzle Stn Shutter] button to

2
Check the detection status of the
nozzle station sensors.
Check to see if the nozzle station sensors
detect the presence or absence of nozzles.
1. Open the [Unit]-[I/O] screen.
2. From the "Input" drop-down list, select
"NZL STATION".
3. While extracting a nozzle from the nozzle
station and returning it to the same
position, check whether the
corresponding sensor detects the nozzle
correctly.
The detection status on the screen should
read "1" when the nozzle is extracted
from the nozzle station, and should read
"0" when the nozzle is in the nozzle
station.

TIP
The nozzle station position No. where a nozzle was
extracted or inserted is displayed on the lower part of
the "Input" status screen.
3
Clean the nozzle station.
If the nozzle detection status is different from
the actual nozzle presence status, remove
the nozzle and visually check the nozzle
setting position. If any dust or chip is found,
remove it and clean the inside of the nozzle
with the vacuum assembly.
c
CAUTION
If the nozzle detection status inside the nozzle station
does not become stable for a reason other than clear
reason, such as dust, etc., or if the nozzle cannot be
detected, contact YAMAHA sales representative.
Disassembly and cleaning of the nozzle station sensors
by the user will void the warranty.
