27 Troubleshooting
Cause:
The shutter is closed.
Remedy:
• Open the shutter.
• Check the setting for “Shutter control” (“I/O” or “Communication
commands”) in the “System settings” of “Laser Marker NAVI smart”.
Make sure the setting matches your current control method.
• A change of this setting will take effect only after restarting the laser
marking system.

File switching has not completed.
Remedy:
During file switching, the marking ready output READY OUT (Y5) is OFF
until the marking data are generated. The time varies depending on the
quantity of data to be marked. Do not input the marking trigger signal
until READY OUT (Y5) is ON.
Cause:
External character input was activated, but the required marking data are
not input from the external device.
Remedy:
• If the register function (registered characters), the external offset
function, or character entry by
SIN
command is used, the marking
data must be input in every marking cycle.
• LP-RC, LP-RF, LP-RV: Before you input the marking data, make sure
the DATA WAIT OUT (No.38) output of the I/O connector is ON.
Cause:
Reception mode was turned on during command control.
Remedy:
Turn off reception mode with the Reception mode (
MKM
) command.
Cause:
LP-RC, LP-RF, LP-RV: The counter was reset during on-the-fly marking.
Remedy:
When the counter is reset during on-the-fly marking, READY OUT (Y5)
temporarily turns off and the trigger signal cannot be transmitted. Check
the timing of the counter reset.
