E752 Cause:
TARGET DETECTION IN (X7) did not turn on during the lasing process.
Remedy:
• Check the marking results before and after the error occurs.
• Check the connection and control of the workpiece detection sensor.
• Check the installation position of the sensor and make sure it is ON
for more than 1ms during the lasing operation.
• When you do not use this function, disable TARGET DETECTION IN
(X7) in the "System settings".

E760 Cause:
• The setting of a number input of the I/O connector failed.
• The set input turned ON more than once before the setting
completion output turned ON.
Remedy:
• Keep the set input SET IN (No. 2) ON until the setting completion
output SET OK OUT (No. 28) turns ON.
• To set the number input again, close the shutter and reset the
previous data.
• Check the connections to external devices for faulty or loose
contacts.
• Check the operation logic of the connected device.
E770 Cause:
Unable to communicate with Laser Marker NAVI smart because there is
no connection between the laser marking system and the PC.
Remedy:
• Check the status of the Ethernet or USB connection.
• For Bluetooth communication, check if there are any obstacles
between the PC and the laser marking system and if the distance
between the two devices is within the allowed range.
• Save the files onto your local PC folder, and overwrite and save
them on the laser marking system after the online connection was
established.
