6.9.2 LD SAFETY SWITCHES
Safety switches are installed at the front and right doors to ensure technician and
user safety and to prevent the laser beam from accidentally switching on during
servicing. Opening of the front or right door opens the corresponding switch,
cutting the power supply (+5VLD) to the laser diode.
The safety switches are installed on the +24V line coming from the power supply
unit (PSU). The +24V supply must pass through these switches before converting
into the +5VLD power that drives the laser.
