4-2-11 Internal shutter
The internal shutter is opened and closed by the rotary solenoid to shut off the path of laser beam.
Effect from deterioration
When the rotation torque of the rotary solenoid declines, the opening/closing speed of the internal shutter is decreased
or the shutter may not work. In this case, an error “Internal shutter failure” occurs in the laser marker and lasing operation
cannot be performed.
Replacement interval
• Total number of opening/closing operations has exceeded two million.
• Alarm for internal shutter error occurred.
How to confirm the number of opening/closing operations
Click “Environ.” on the right menu and click “System info”.
The total number of the shutter operation is displayed on the screen.

4-2-12 Battery inside the controller
A lithium primary battery is contained inside the controller as battery for clock or calendar of the laser marker. Based on
this internal clock, marking characters such as the current date/time, expiry date/time, and lot date/time are updated.
Effect from deterioration
When the battery inside the controller runs out due to aging, the date and time of the internal clock may be out of
synchronization when the laser marker is turned OFF. If you start the laser marker in such a condition, the warning for
internal clock (E251) may occur and the date and time setting is required. This warning is generated every time the laser
marker is started until the internal battery is replaced.
Replacement interval
• Warning for internal clock (E251) occurred.
• Almost five years have passed since delivery.
