ADF
17. 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. The
paper eject/reverse motor stops when the paper eject/reverse sensor
goes off and the transportation motor stops when the document
bumps against the paper stopper. Document transportation stops
when the flapper solenoid goes off. With the document set for scan,
the ADF sends the paper feeding complete signal to the scanner, and
the scanner starts scanning.
18. After scanning, the ADF starts transporting the scanned document
back to the scanning position via the paper eject/reverse mechanism.
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.
19. 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.
20. 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. The
paper eject/reverse motor stops when the paper eject/reverse sensor
goes off and the transportation motor stops when the document
bumps against the paper stopper. With the document set for scan,
the ADF sends the paper feeding complete signal to the scanner, and
the scanner starts scanning.
