    2-1-3 Original switchback/eject sections The original switchback/eject sections consists of the parts shown in figure. An original of which scanning is complete is ejected to the original eject table by the eject roller. In the case of duplex switchback scanning, an original is conveyed temporarily to the switchback tray and conveyed again to the original conveying section by the switchback roller.

  • Page 100: Reverse Duplex Scanning Operation

    (1) Reverse duplex scanning operation In the double-sided original mode, after the first side of an original is scanned, the feedshift guide is activated to switch the conveying path to the switchback tray side and the original is fed to the switchback tray. Then, the original is reversed by the reverse rotation of the DP paper feed motor (DPPFM) and conveyed again to the original conveying section.
