InFocus Laser Platform M-300 - Manual (Page 93)

7-6 Maintenance
Beam Window
The Beam Window is where the laser beam enters into the engraving area. It is located in the
upper left hand corner of the engraving area against the back wall and is yellow in color. It is not
necessary to remove the Beam Window for cleaning since it can only get dirty on the front side.
The backside is in a sealed environment. To clean the Beam Window, moisten a cotton swab
and gently roll it across. Basically, clean it in the same manner as the #2 Mirror.
AUTOFOCUS Sensor and Reflector (if installed)
Engraving smoke can adhere to both the sensor and the reflector of the AUTOFOCUS system.
If this happens, you will notice that when you turn AUTOFOCUS on and press the “Z” button, the
engraving table will go all the way down to the bottom and get stuck. You will then need to call
our service department so that we can assist you into getting the system back to normal
operation. To prevent this problem from occurring, you should clean the sensor and reflector
periodically. How often you clean them is dependent on the types of materials you are engraving
and the quality of your exhaust system. The diagram below shows the locations of these parts.

To clean these parts, dampen a soft cotton cloth with water and gently wipe across the reflective
surface in one direction. DO NOT rub hard or create scratches in the plastic, otherwise the
AUTOFOCUS system will malfunction. DO NOT use any type of cleaners, only use water or a
light solution of hand soap and water on the sensor or reflector.
You can observe if the sensor is working properly by lowering the table so that you have clear
sight of the sensor and the reflector. Look at the sensor and notice that the green LED will
illuminate. Pass your hand in front of the sensor and watch the red LED turn on as your hand
passes through the path, and the red LED will turn OFF when your hand clears the path.
Contact our service department if you have any other concerns about the operation or
maintenance of the AUTOFOCUS system.
