Paper ejecting mechanism

Outer chute
Jam sensor actuator
After the paper passes through the heat-fixing process, it will be ejected from the heat-fixing unit by
the paper ejection roller.
If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the sensor
signals the start of paper ejection. If the trailing edge has passed through the sensor actuator, the
sensor signals the completion of paper ejection.
If the jam sensor actuator will not be pushed up within the specified period after the leading edge of
the paper pushes down the paper ejection sensor actuator, then the controller will interpret such an
event as a paper jam inside the heat-fixing unit and display a jam error on the LCD.
The paper will be turned over along the outer chute and ejected onto the main cover by the exit
roller.
