16-4 Nozzle offset
16-4-1 Nozzle offset
This nozzle offset function captures the image of the dispense point that has been dispensed on the dot
station, processes this image, and corrects the installation error between the dispense head and nozzle.
There are two kinds of nozzle offset acquisition methods, auto and manual.
16-4-1-1 Dispense data, Dispense Library - Dispense Check, and Image Library (image data) setting
The dispense check parameters used to dispense onto the dot station can be used as they are. It is not
necessary to create new parameters.
16-4-1-2 Auto acquisition
When the production starts, the nozzle moves down to push the roll paper on the dot station so as to
acquire the nozzle offset in the Z-direction.
Next, the dispense is performed onto the roll paper on the dot station to acquire the nozzle offset in the
XY-direction.
This nozzle offset is acquired at the same time when the dispense check is performed.
If the cover is opened and closed during production, the nozzle offset is acquired automatically when the
production is restarted.
Note: An [Auto] dispense check occurs during production when the Placement & mark (program) contains a
"dispense check" (dot station) step.
Nozzle offsets are also acquired when this dispense check occurs.
Therefore, no particular operation by the user is required.
16-4-1-3 Manual acquisition
Menu: Manual>Dispense

② In this window, click the <Get Z Offset> button in the [Offset Acquisition] area.
the nozzle moves down to push the roll paper on the dot station so as to acquire the nozzle offset in
the Z-direction.
③ Next, select a dispense code and click the <Get XY Offsets> button.
The dispense is performed onto the roll paper on the dot station to acquire the nozzle offset in the
XY-direction.
④ The acquired nozzle offset values display at this screen's [Offset] item.
Note: Acquire the nozzle offset under dispense conditions with proper dispense area and dispense shape.
In particular, if the dispense shape is incorrect, such as fluid stringing or ellipse, the center of the dispense
point deviates, causing an error.
Note: An [Auto] dispense check occurs during production when the Placement & mark (program) contains a
"dispense check" (dot station) step.
Nozzle offsets are also acquired when this dispense check occurs.
Therefore, this manual acquisition operation should be used for nozzle offset tests.
