To ensure technician and user safety and to prevent the laser beam from

inadvertently switching on during servicing, safety switches are located at the front

and right covers. The switches are installed on the +5VLD line coming from the

power supply unit through the SBCU and IPU boards.

When the front cover or the right cover is opened, the power supply to the laser
