Perform the marking time measurement.
If “Line speed control” is set to “Encoder input” or “2 sensors input”, specify the
approximate line speed for test marking and measure the marking time.
If you use an automatic switching function for the marking data, perform the marking
time measurement with characters that consist of many lines or curves such as the
number “8”.
In the measurement result of the marking time, the moving time of the workpiece is
included. The measurement result shows the time required from the commencement
of input of the marking start signal until the completion of the marking process.

Make sure that no error with on-the-fly marking occurs.
• If an error occurs because the marking speed cannot follow the line speed, specify
an upstream position (positive value) for the lasing start boundary.
• It is not necessary to conform the lasing start boundary to the position of the
marking data in the marking field.
• If there is no on-the-fly marking error, the recommended position of the lasing start
boundary is the center of the marking field (default setting).
• If the problem with on-the-fly marking cannot be resolved, try the following:
‒ Reduce the marking time by increasing the scan speed, for example.
‒ Reduce the line speed.
‒ Increase the distance to the next workpiece.
