The feed motor feeds the separated original to the registration roller [A]. A short time after an original
reaches the registration sensor [B], the DF feed motor stops briefly, the scanner moves to DF scan position,
and the white peak is read. The DF feed motor and DF transport motor then start and the sheet is scanned.
After scanning, the original is fed out by the exit roller [C].
Double-Sided Originals
After an original has been fed to the registration sensor [B] by the transport roller [A], the DF feed motor
stops briefly. After the scanner has moved to DF scan position, and the white peak has been read, the front
side of the original is then scanned.
When the exit sensor [C] detects the leading edge of the original, the junction gate solenoid is activated
and the junction gate [E] opens. The original is then transported towards the inverter table.
Soon after the trailing edge of the original passes the exit sensor, the junction gate solenoid switches off
and the junction gate [E] is closed. When the original has been fed onto the inverter table, the feed and
transport motors stop. After that, the feed motor rotates in reverse and the original is fed to the exit roller
[D] by the inverter roller [F]. At this time, the feed motor stops briefly to adjust the original skew.
After adjusting the original skew, the original is fed again by the exit roller [D] and registration roller [B]
to the scanning area (where the reverse side will be scanned).
