9. Making a test print
When visual alignment on the created data has been made, make a test print before starting board
production, to check the printing conditions and accuracy and make necessary adjustments. In test print, we
recommend covering the board with a transparent sheet (option) to protect the board just as with the rolling
operation.

Note
When printing with newly created board data, always make a test print before starting production to check the
printing conditions and accuracy. Even when printing with board data you have used, we recommend making a test
print before beginning daily work.

automatically recognized. (The mark recognition process is skipped if not using the fiducial mark
function.)

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.
