2. On the manual board check screen, select the coordinate from which you want to start checks.
3. Press the [Trace] button to start visual checks.
The printed state at the selected coordinate is displayed on the vision display. Check the position
and area of the printed solder versus the land pattern. Using the [Auto] button allows continuous
trace of the inspection coordinates that were set.

Check the settings for printing motion. Refer to the "Printing Guide" at the end of this manual for how to set the
"Squeegee pressure" and "Squeegee speed" parameters.
Printing position deviations are described in the next step.

Adjust the print position errors.
Open the [Print]-[Squeegee] tab and adjust the following parameters.
Enter the positional offsets in the Mask Offset X, Y and R parameters according to the position errors.
(Mask Offset Z adjustment is not necessary here.)

Printed state Offset entry
When shifted to right In Offset X, enter the position error (mm).
When shifted to left In Offset X, enter the position error (mm) with a minus sign.
When shifted to upper side In Offset Y, enter the position error (mm).
When shifted to lower side In Offset Y, enter the position error (mm) with a minus sign.

Clean the mask.
When the test print is complete, clean the mask.
1. Open the [Unit]-[Cleaner] tab and press the [Auto Cleaning] button.
A dialog box appears asking you to select the cleaning method.
2. Select the cleaning method ("Dry" or "Wet") and press the OK button.
The cleaning unit begins moving to clean the backside of the mask automatically.
TIP
When you want to perform manual cleaning, press the [Manual Cleaning] button and follow the message that
appears.
