(2-1) 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.
