(3) Confirming the presence of reflecting light 

 

With the segment set to 1, close the shutter of the emission unit on the X axis, 
then check that the reflection light from the Y axis will not be directed into the 
reception window of the X axis. Allow 5 to 10 minutes for this check of the 
reflecting light as scanning beams from the X axis and the Y axis are 
asynchronous.  
Under the normal state, the Err-0 message will be displayed. 
Perform the same check with the Y axis. 

 

With the oscilloscope connected to the monitor connector on the rear panel of the 
display unit, it is also possible to check for the presence of the reception signal 
due to the reflection light. For a model with a visible laser beam, the reflection light 
can be checked by placing a piece of paper on the reception window.
