7.Detailed Descriptions
Back Side
After a certain time passes since the original reached the ARDF feed sensor [A], the original exit roller
[B] is reversed and the back side of the original is fed. There is no switching mechanism such as a
junction gate; the original is delivered to the duplex scanning path by the curved surface of the paper
path.
The image information of the back side is scanned on the sheet-through glass and the original is
ejected by the transport roller.
