1. One-sided Original Feed
When the start key is pressed after an original is set face down on the
original table [A], the bottom sheet of the original stack is fed onto the
exposure glass [B] by the rollers [C] and the transport belt [D].
After the scanner scans the original on the exposure glass, the transport belt
and the exit rollers [E] feed out the original to the original tray [F].
2. Two-sided Original Feed
In two-sided original feed mode, the inverter gates [G] are open. After the
scanner scans the front side of the original, the original is inverted around the
inverter roller [H] and transported to the scanning position again by the
reversing transport belt.
After both sides of the original are scanned, it is transported to the switch
back tray [I] while the switch back gate [J] is at the lower position. This is to
return the inverted originals to their original page order. Then the original is
fed out to the original tray.
