■ Processing Tray Path
This is the copy ejection path when the equipment is set to sort for paper size other than A4,
B5, or LTR or when set to staple sort.
Copies are delivered to the processing tray for aligning and stapling. Then they are ejected
using the rear end assist.

■ Buffer/Processing Tray Path
This is the copy ejection path when the equipment is set to sort for A4, B5, or LTR paper size.
Feed two sheets of paper to buffer (two or three sheets if 2-point stapling).
Then they are aligned and stapled in the processing tray and ejected.
Even while stapling or offset is being performed, simultaneous stack ejection, which
simultaneously ejects copies delivered to the buffer and post processed stack in the
processing tray, is performed because copies are received continuously from the host
machine.
The stack delivered from the buffer is ejected to the processing tray and the stack processed
in the processing tray is ejected to the tray.
Simultaneous stack ejection operation is described below for two A4 copies between stacks
when the equipment is set to sort.
1) When the 1st paper reaches the switchback point, it is sent to the buffer unit and the rear
end of the paper is held by the buffer guide.
