Operation of original switchback
In the double-sided original mode, the switchback feedshift solenoid (SBFSSOL) turns
on, changing the position of the switchback feedshift guide. This switches the path of
the original to the original switchback section to where the original is fed.
The switchback feedshift solenoid (SBFSSOL) then turns off, allowing the switchback
feedshift guide to return to the original position by which the path of the original is
switched back to the original conveying section. The now reversed original is carried to
the original conveying section and the switchback pressure solenoid (SBPSOL) turns
off, releasing the switchback pulley to prevent an original jam in the original switchback
section.
