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.

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.
