When the paper is sent to the duplex section, the duplex paper tapping solenoid
(DUPPTSOL) lowers, which forwards the paper by means of the rotation of the duplex
forwarding pulley until it is caught by the switchback roller.
In duplex copy mode, the switchback feedshift solenoid (SBFSSOL) turns on to operate
the switchback feedshift guide. The paper is then sent to the duplex paper conveying
section by the rotation of the switchback roller.
During switchback ejection, the paper is conveyed to the feedshift and eject section and
ejected with the copied face down.
