Daily maintenance items

1. Checking the nozzle

Solder sticking to the nozzle tip or a clogged nozzle hole can cause component pickup errors and

recognition errors. Poor nozzle spring action can also cause pickup and mounting errors. To prevent such

problems periodically inspect and clean each nozzle.

1.1 Check with software

■ How to check for a dirty nozzle (with the [Check Nozzle] button)

The term “dirty nozzle” as used here indicates shiny material such as solder adhering to the nozzle tip. This shiny

portion might be mistaken for a component and cause recognition errors. To check for this problem, press the

[Check Nozzles] button on the [Setup] screen while the nozzle tip picks up no components. The multi-vision

camera finds the extent of grime or dirt on the nozzle tip.

Move the head.

Press the emergency stop button and move the

head so the nozzle is at a position where it can be

easily replaced.

Press the [Check Nozzles] button as

follows.

1. Cancel emergency stop.

2. Open the [Setup] screen and press the [Check

Nozzles] button in "Utilities".
