Nozzle holder

A ball and spring 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 spring and ball inside the nozzle holder carefully, since they tend to get lost. It is

recommended that spare parts should be kept handy and start removal.

ACTION:

① Remove the spring holder with a flat blade screw.

NOTE: Adhesive has been applied around the screw head to prevent loosening. When removing the spring holder

for the first time, take off the adhesive and start removal.

② Take the spring and ball out.

(When it is difficult to take the ball out, push it from inside of the nozzle holder.)

③ Remove the spring from the spring holder with tweezers.

④ Remove dust and dirt around the hole area, the spring and ball.

⑤ Apply the proper amount of Silicone Grease to the spring and ball.

Put them back in reverse order of removal. Fasten the spring holder until it touches the inner wall.

ACTION:

① Wipe off oil, dust, or water from the upper side of the nozzle flange with alcohol.

② Slide the ring of the labeler until the groove in the labeler shaft appears.

③ Peel off the sticker from its slip sheet using tweezers.

④ With the sticker’s adhesive side upward, align the sticker’s angle mark to the ring’s positioning mark.

Set the sticker into the ring, being careful not to touch the sticker’s adhesive side.

⑤ Make sure the sticker is properly placed in the ring.

Cleaning Nozzle Recognition Stickers

Dirt on nozzle ID/presence stickers can be a cause of vision recognition failure. Regularly clean the nozzle

ID/presence stickers.

ACTION:

② Wipe off the remaining alcohol on the sticker with dry cotton swab.

NOTE: Particularly the nozzle ID stickers are liable to get dirty. If a nozzle ID sticker becomes too dirty to be

cleaned, replace it with new one.

For the part No. for the nozzle ID sticker, refer to “5. Materials”.

NOTE: The nozzle ID/presence stickers are easily peeled off when they get wet. Be sure to dry them with cotton

swab whenever they get wet.
