Inspect the Nozzle Plate for Cleanliness
It is important to inspect the jet nozzle plate for debris before mounting it onto the Jet.
A clean nozzle looks like this:
If the nozzle plate is not clean, it could affect the dispensing quality. These dispensing
problems are symptoms of a contaminated jet:
Unclean or uneven dispensing
Drops become irregular or vary in size
Residual flow or drooling out of the tip when the jet is in the closed position
Interrupted dispensing (places where fluid no longer is dispensed)
Splatter or satellites
For best results, Advanjet cleaning kits contain tools appropriately sized to the nozzle
plate. For example, if you are using the 125
μ
m nozzle plate, order the 125
μ
m cleaning
kit (Advanjet P/N CL-125).
Refer to Section 4 for complete instructions on cleaning the jet.
NOTICE
Never submerge the diaphragm in solvents as it might result in damage.
Diaphragms can be cleaned successfully with
a small amount of solvent and a soft brush and cotton swab.
Do not submerge the diaphragm into the ultrasonic cleaner because
it will deteriorate the diaphragm and shorten its life.
