2. DESCRIPTION OF OPERATION
2.3.1.4 Document detection
Document present/absent detection
Document present/absent detection on the document tray is performed by document set
sensor (PI14). When a document is placed on th edocument tray, the detection lever moves
together with the light-shielding plate so that photo interrupter that has been passing the light,
shut down the light. Thus, the document set sensor (PI14) issues the document detection
signal (SET) telling that a document is set, to the connected equipment via the ADF relay
PCB.
Detection of final document
The final document detection sensor (PI14) detect if the document that has started of the
final document has passed the set sensor lever, the detection lever moves together with
the light-shielding plate so that the photo interrupter that has been shtting down the light,
passes the light. Thus, the document set sensor (PI14) issues the final document detection
signal (SET) telling that the document under feeding is the final document, to the connected
equipment via the ADF relay PCB.
