2.6 PAPER HEIGHT AND END DETECTION

2.6.1 PAPER HEIGHT DETECTION

Two paper height sensors [A] [B] and actuator [C] are built into the paper tray lift motor.
The paper height sensors, detect the amount of paper in the tray.
The actuator [C] has two semicircles, and it is engaged with the lift arm shaft via gears.
The paper height sensors detect the paper size depending on the position of the two
semicircles. The list shown below shows the detection combination of the two sensors.
The paper remaining status bar is displayed in the tray selection icon on the LCD.
