ADF Operating Principles
Rev. A

9. According to the reverse feeding command, the transportation motor
and the paper eject/reverse motor rotate forward to transport the
scanned document to the paper eject/reverse mechanism and the
flapper solenoid comes on to switch the paper path to the paper
eject/reverse mechanism side.
10. When the paper eject/reverse sensor comes on, the transportation
motor stops and then the paper eject/reverse motor stops to hold the
document in the paper eject/reverse mechanism.
11. The transportation motor rotates backward and then the paper
eject/reverse motor rotates forward to transport the document from
the paper eject/reverse mechanism to the scanning position on the
platen glass. The paper eject/reverse motor stops when the paper
eject/reverse sensor goes off. When the document bumps against the
paper stopper, transportation motor stops and the flapper solenoid
goes off to stop transporting the document. With the document set for
scan, the ADF sends the paper feeding complete signal to the
scanner, and the scanner starts scanning.
12. After scanning, the ADF starts ejecting the scanned document and
transporting the pre-fed document according to the reverse feeding
command. The transportation motor and the paper eject/reverse
motor rotate forward to transport the document to eject it.
