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.

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.

Check that the blow air is being
exhausted correctly.
To check if the blow air is being uniformly
exhausted from each air joint on the lower
part of the ejector unit, open the [Unit]-
[Head] tab and press the [Blow] button for
each head.

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.
