ADF Operating Principles
Rev. A

9. After scanned, the scanned document is ejected according to the
single feed command from the scanner and the pre-fed document is
transported to the scanning position.
10. After the document is fed by the forward rotation of the transportation
motor and the paper eject/reverse motor, the paper feed motor
rotates backward to transport the document onto the platen glass and
stops when the timing sensor goes off.
11. After the paper feed motor stops rotating, the transportation motor
transports the document and stops rotating when the rear edge of the
document passed the document stopper. In case the empty sensor
goes off while the document is transported, the shutter solenoid goes
off. The ADF continues to eject the scanned document.
12. Transportation motor rotates backward to feed back the fed
document to align it with the document stopper causing impact, then
the transportation motor stops. With the document set on the
scanning position, the ADF sends the paper feeding complete signal
to let the scanner start scanning. The ADF continues to eject the
scanned document.
