6.7.2.4 Operations done during laser height check/measurement
① Head used to pick up a component
The system automatically selects a head which is used to pick up a component.
The system selects a nozzle already attached on a head rather than one not
attached so that the frequency of nozzle replacement can be reduced.
However, the system may use a different head every time it measures laser
height depending on the nozzle attachment condition.

② Returning a component after check
After checking laser height, the system returns some components onto their
original positions and discards other ones depending on their packaging style
as shown in Table below. When the setting item “Compo Reject to”, indicating
the component discarding method, is set to “Trash conveyor” or “Protect”, the
system discards a component according to this setting. The system discards a
component on a position which is set with the "Compo abandonment" selection
of Component data. For a component whose size is 1 mm or less, it may be
placed on its side or be turned upside down when it is returned onto the original
position. Therefore, the system asks you how to handle it.

*1 The system displays the dialog box which asks you whether to return a
component or discard it. In Continuous measurement mode, the system
displays this dialog box before starting measurement operation.
*2 The system discards a component when the setting item “Compo Reject to”
is set to “Trash conveyor” or “Protect”.
③ Selecting a feeder used to pick a component
If two or more feeders are assigned to the same type of components in Pick
data, the system, as the default setting, starts picking up components from one
whose data was entered first of all. Only in Single check mode, you can
change the feeder intentionally.
④ Changing the coordinates of a pick-up position
When a component is not picked up properly, manually enter the coordinates or
use the HOD device to teach them to change the coordinates of a pick-up
position.
⑤ Manual component pick-up
If there is no Pick data created, you can manually attach a component to the
nozzle. However, in this case, you cannot enter coordinates that indicate the
component pick-up position. You cannot operate a feeder either.
