Cooling Fan
The cooling fan [A] at the back of the machine blows air through the duct [B] and sends it above and below
the laser exposure unit. The fan switches on and off with the polygon motor.
The air [C] above passes through a dust filter before it reaches the optical path. The air passing below [D]
flows over the top of the fusing unit and is expelled by the fusing cooling fan.
The polygonal mirror motor [E] normally remains on. It shuts down when the machine is powered off or
enters the auto off mode or night mode.
LD Safety Switches
To ensure the safety of customers and customer engineers, two switches inside the cover prevent the laser
beams from switching on accidentally.
