1. Checking the nozzle
Solder sticking to the nozzle tip or a clogged nozzle hole can cause component pickup error and recognition
error. Inspect each nozzle periodically to prevent the errors.

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. Regarding RS head, this function is available with machine equipped with multi-camera.
n
NOTE
The [Tip Dirt Check] is a function that recognizes the reflection of the light around the nozzle center. Therefore,
applicable nozzles are those with a small tip, such as Type 501A and 502A.
n
NOTE
As the nozzle type may vary depending on the machine, some machines may require additional settings. Contact
YAMAHA sales representatives for details.

How to check for clogged nozzles (on the [Unit]-[Head] tab screen)
The term "clogged nozzle" used here indicates that material such as solder is adhering to the nozzle hole, causing a rise
in negative pressure even if no component is being picked up by the nozzle. This state might cause problems such as
component mounting errors. Check for clogged nozzles with the following procedures.
As the procedures of MU head, FL head and RS head differ, each procedure is described separately.

the [Head] tab. If the value is 75 or less, it
is in normal range.
2. If the value is higher than 75, the nozzle
hole might be dirty. See "1.2 Nozzle
