5.5 LD SAFETY SWITCHES
To ensure that the laser beam does not accidentally switch on during
servicing, there are two safety switches located at the front door. These two
switches [A] are installed in series on the LD 5 V line coming from the dc
power supply board.
When the front cover is opened as shown above, the power supply to the
laser diode is interrupted.
