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.

How to check for a dirty nozzle (with the [Tip Dirt Check] 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. [Tip Dirt Check] is a tool that
judges the nozzle contamination status by recognizing the nozzle tip in the non-component status with the
camera.
n
NOTE
[Tip Dirt Check] is a function that recognizes the reflection of the light around the nozzle center. So, applicable nozzles
are those with a small tip, such as 301A, 302A, and 311A.

NOTE
Since the nozzle specification may vary depending on
the machine, some machines may require additional
settings. For details about settings, contact YAMAHA
