3.2.2 Checking the negative pressure
Aftercleaningthesplineshafts,checkthenegativepressure(vacuumlevel)generatedineachhead.
1
After assembly, check the vacuum
levels.
1. Leave nozzles detached from the heads.
2. Open the [Unit]-[Head] tab screen and
press the [Vacuum] button to generate a
negative pressure. Read the "Max" values
shown on the screen and determine
whether the vacuum levels are
appropriate by referring to the criteria
below.

Reattach the nozzles.
Attach the nozzles by hand back to the
heads.

NOTE
The vacuum level in the spline shaft air path might sometimes differ slightly depending on the air source and operating
conditions. Use the above criteria for reference during maintenance.

1
Turn off the machine power switch.
Quit the software and turn off the machine
power switch.
2
Move each spline shaft by hand to
check for abnormal movement.
Move each spline shaft up and down by
hand and make sure that all spline shafts
move smoothly without hanging up and
unusual noise.

Clean the outside of each spline
shaft.
Use a lint-free cleaning wiper or cotton swab
to wipe the outside of each spline shaft.
4
Apply grease to the outside of each
spline shaft.
Apply a thin, uniform coat of grease by hand
to the outside of each spline shaft.
