b. Cleaning the nozzle

1. Remove dust in the air pass of the

nozzle with the air ejector.

∗ Blow the air to the nozzle tip.

At this time, be careful not to touch the nozzle

tip with an air ejector. It may damage the

nozzle tip.

2. Clean the nozzle taper face with a

cloth.

∗ Be careful not to leave the fiber on it.

3. Clean the nozzle tip (nozzle) with a

cloth.

4. Clean the nozzle reflector with a cloth.

∗ Do not use any solvent because it may cause

discoloration, deformation and peeling of the

glue of the nozzle reflector.

∗ The nozzle is not allowed to accept an ultra-

sonic cleaning. If it accepts the ultrasonic

cleaning, the nozzle reflector will corrode to

cause a chip recognition error.
