Paper Transport – Two-sided Originals

Two-sided Transport Details

After an original has been fed to the registration sensor by the transport
roller, the DF feed motor stops briefly.

After the scanner moves to DF scan position, the front side of the
original is scanned.

When the exit sensor detects the leading edge of the original, the
junction gate solenoid is activated, opening the junction gate.

The original is then transported towards the inverter table.

After trailing edge of original passes the exit sensor, the junction gate
solenoid switches off and the junction gate is closed.

Following feeding of the original onto the inverter table, feed and
transport motors stop.

The feed motor rotates in reverse and the original is fed to the exit roller
by the inverter roller.

Feed motor stops briefly to adjust original skew. After adjusting, original
is fed again by exit roller and registration roller to the scanning area
(where the reverse side will be scanned)

Original is then sent to inverter table again to be turned over, enabling
duplex output to be properly stacked front side down in the exit tray.

See technical drawings on following pages for illustrations of ARDF operation.
