1 Move the laser head to the top left corner. Lift the honeycomb tray by the handles on both sides then take it out.
Mind the sharpness of the honeycomb surface to avoid cut ting injury when taking it out.
2. Use vacuum cleaner or brush to clear the leftovers bits under the tray. Detergent can be applied to remove the stains.
3. Return the tray to the original location, sliding it in horizontally. Be careful not to contact the laser head or the rails.
