● Cleaning Nozzle holder

A roller and leaf springs that hold the nozzle may not perform smoothly due to the entry of dust and dirt,

which will cause a nozzle dropping. Make a periodic check of the nozzle escape. If any *abnormal

conditions are seen, clean the nozzle holder. (*The nozzle stays up and does not go back to its initial

position, or the nozzle drops easily etc.)

NOTE: Please handle the roller and leaf springs inside the nozzle holder carefully, since they tend to get lost. It is

recommended to keep these spare parts handy before starting replacement.

ACTION:

① Unscrew the two screws with a Phillips screwdriver to take the roller and leaf springs off.

② Remove dust and dirt around the area where the roller touches, the roller and leaf springs.

Check to see that there is no flaw in them. (Replace the part with a new one if there is a flaw)

③ Apply the proper amount of Silicone Grease to the roller and the area where it touches.

Put them back in reverse order of removal.

● Cleaning interval

Clean nozzle holders once or twice a month. In case of unusual conditions are seen when checking

nozzle-holder escaping, clean nozzle holders.

NOTE: A life of the leaf spring is approximately five hundred thousand nozzle changes. It should be replaced

periodically. The recommended period is one year.

■ Application of grease on a Nozzle Holder

ACTION:

① Rub the inside of the Nozzle Holder with materials like a dry cotton swab to clean out the grime, such

as old grease.

② Use the head vacuum breaker to blow out the dust, such as fibers from a cotton swab.

NOTE: The head vacuum breaker can be executed by clicking the button at required head on the window of Main

Menu > Manual Menu > Actuator > On/Off > Head Vacuum.

③ Apply silicon grease evenly on the new cotton swab and rub the inside of the Nozzle Holder softly and

evenly with it.

④ After grease is applied, insert a nozzle and confirm that the nozzle escaping works smoothly.

● Replacing seals of nozzle holders

Seals are attached on bottoms of nozzle holders to prevent from being recognized as nozzles when “Scan

Nozzles” is performed.

Long-term production doing nozzle exchange may cause seal damage such as scratches and wear.

Damaged seals may cause light reflection which occurs vision recognition errors. In this case replace

damaged seals with new ones.

■ O-ring

If the O-ring inside the nozzle deteriorates and develops cracks, air leakage will occur. This will reduce the

maximum air pressure (negative pressure), causing problems with suction operation. If the reduction in the

maximum air pressure is found and the cause seems to be in the nozzle, replace the O-ring inside the nozzle.

ACTION:

① Pull out the O-ring from the nozzle and clean inside the nozzle with an air blower.

② Insert a new O-ring into the nozzle from its rear end.

③ Push the O-ring against the bottom inside the nozzle.

④ After the new O-ring has been set in place, attach the nozzle to the head and check for nozzle

clogging.

)

Checking the nozzle for clogging

NOTE: Do not apply silicon grease or the like to the O-ring since it may cause nozzle clogging.

■ Nozzle Filter

The nozzle filter prevents dust from getting inside the nozzle. It also prevents the escape action malfunction

caused by the dust. Periodical cleaning of the nozzle filter must be performed.

ACTION:

① Clean the nozzle with an air blower from its rear end.

NOTE: Normally, cleaning with the air blow may be enough. But when the dirt is firmly fixed, remove the O-ring

and the filter to clean.

NOTE: Nozzles with filter:

P005, P006, P013, P018, P019, P020 and Custom-made nozzles.

Dust and dirt are easily taken in to a nozzle hole with a big-diameter. (1.0mm or more)
