• When an original is placed in the original tray, after the pickup roller drops and the bottom plate position sensor goes OFF, the bottom plate lift motor [A] turns ON and pushes the lift lever [B] against the bottom plate to raise the bottom plate.
  • When the bottom plate position sensor [D] goes ON, the bottom plate lift motor [A] stops.
  • When the height of the stack diminishes low enough during continuous original feed for the bottom plate position sensor [D] to go OFF, this signals the machine to switch the bottom plate lift motor [A] ON again to raise the tray.
  • This mechanism keeps the position of the top of the stack (up to 250 sheets) at the correct position for continuous original feeding.
  • After the last original is fed, the bottom plate descends as far as the bottom plate HP sensor [C], and the motor turns off.
