(1) Operation of original switchback

In the double-sided original mode, after the first side of an original is scanned, the switchback 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 original switchback motor (OSBM) and conveyed again to the original conveying
section. After the second side is scanned, the original is fed temporarily to the switchback tray, is reversed, is conveyed
without scanning, and then is ejected to the exit tray. Also the switchback press solenoid (SBPSOL) is activated to
release the switchback pulley for preventing original jams in the original switchback section.
