Power Supply Section Cooling Mechanism

• A cooling fan motor draws air from the area around the Power Supply Unit to the outside
to prevent the Power Supply Unit temperature from running high.
• The cooling fan motor is turned at full speed when the Main Motor turns and at a speed
reduction during other timings, thereby making the machine quieter without sacrificing
cooling performance.
