3. OPERATION
3.1 Document feed section
3.1.1 Document set/empty detection
• When an original is loaded on the document feed tray, the document empty sensor detects that there is original.
• If no original is loaded when the document pick-up roller is in the standby position, the actuator blocks the document empty sensor and it is
detected that no original is loaded.
• When an original is loaded on the document feed tray, the leading edge of the original pushes the actuator so that the document empty
sensor is unblocked. It is detected that an original is loaded.
• When all pages of the original are fed in, the document empty sensor detects that there is no original on the document feed tray.
