1
Move the head all the way to the
front end of the Y axis.
On the [Unit]-[Head] tab (or [conveyor] tab)
screen, press the [Axis] button to open the
"Move Axis" screen. Then move the head
assembly all the way to the front of the Y
axis (front of machine).
TIP
The ejector unit is located at the front of the head
assembly. It is easier to inspect the ejector filters when
the head assembly is positioned to the front side of the
Y axis. (Inspect the ejector filters from the front of the
machine.)

2
Press the emergency stop button.
The machine should be in emergency stop
to ensure safety during work.
3
Remove the filter cap.
Loosen and remove the filter cap with a

Clean the filter.
Use tweezers to take the filter out of the
ejector. When there is only a little dust in the
filter, use an air blow gun to blow it away
and return the filter back to the original
position.

NOTE
If there are heavy dust deposits in the filter or the filter
has discolored, replace it with a new filter (K46-M8527-
C0X). As a general guide, filters should be replaced
once every 3 months, although this depends on the
actual operating time.

Reattach the filter cap.
1. Fit the filter into the filter cap and insert it
into the ejector.

Check the ejector vacuum level.
1. Open the [Unit]-[Head] tab.
2. Press the [Vacuum] button while blocking
each air joint with your finger.
3. Make a note of the "Max" reading of
each head while the air joint is blocked,
and check that the reading is higher
than the criterion value below.
Make the same check for all heads.

TIP
If the vacuum level of any head does not reach the
criterion value, then check the air path in the head
(interior of the spline shaft or air hose between the
ejector and spline shaft). Clean or replace it if
necessary.

1
Remove the nozzles from all heads.
c
A strong air flow is exhausted during the cleaning blow.
Always remove all nozzles attached to the heads before
starting the cleaning blow. Starting the cleaning blow
while the nozzles are still attached may blow the
nozzles away from the heads causing the nozzles to
break or become lost.
2
Operate the cleaning blow valves.
1. Open the [Unit]-[I/O] tab.
2. Select [Head] from the Output dropdown
list and select the address for the head
shaft blow (T003C000).
3. Press the [ON/OFF] button
to operate the
cleaning valves of all heads.
