1. Checking the nozzle
Solder sticking to the nozzle tip or a clogged nozzle hole can cause component pickup errors and
recognition errors. Poor nozzle spring action can also cause pickup and mounting errors. To prevent such
problems periodically inspect and clean each nozzle.
1.1 Check with software
■ How to check for a dirty nozzle (with the [Check Nozzle] button)
The term “dirty nozzle” as used here indicates shiny material such as solder adhering to the nozzle tip. This shiny
portion might be mistaken for a component and cause recognition errors. To check for this problem, press the
[Check Nozzles] button on the [Setup] screen while the nozzle tip picks up no components. The multi-vision
camera finds the extent of grime or dirt on the nozzle tip.
1
Move the head.
e
Press the emergency stop button and move the
head so the nozzle is at a position where it can be
easily replaced.
2
Press the [Check Nozzles] button as
follows.
1. Cancel emergency stop.
2. Open the [Setup] screen and press the [Check
Nozzles] button in "Utilities".

NOTE
The machine equipped with a the nozzle station will automatically
change the nozzle and run a check, so step 3 listed next is not required.
3
Change the nozzle.
Press the [OK] button for nozzle change while
following the message on the screen. Nozzle
change begins after pressing the last [OK] button.

■ How to check for clogged nozzles (on the [Unit] tab screen)
The term “clogged nozzle” used here indicates that material such as solder is adhering to the nozzle hole, causing
a rise in negative pressure even if there are no components present. This state might cause problems such as
component mounting errors. Check for clogged nozzles using the following procedure.
1
Attach the nozzle.
e
Press the emergency stop button and attach Type
82A nozzles to all heads. When the machine has a
nozzle station, press the [Nozzle Change] button to
change the nozzles.

2
Reset the numerical figure.
Press the [Reset] button on the lower right of the
screen to reset the pickup level values.
3
Generate negative pressure.
Select [Unit] - [Head], and set the [Vacuum]
buttons for all heads to ON. When this value starts
rising, wait 5 to 10 seconds and set to OFF.
4
Note this figure.
When a figure appears in red on the head screen,
make a note of the “Max” reading. If this figure is
130 or below then it is within normal range. If this
figure exceeds 130 then the nozzle hole might be
dirty so clean it.

NOTE
The above example is for Type82A nozzles so the figures shown will be
different for other types of nozzles. (Example: Type 81A = 180)

NOTE
If a correct figure cannot be obtained after cleaning even after
performing steps 1 to 4, then the interior of the spline shaft might be
dirty.
