Normally the page is fed out directly face-up to the output tray. If the user selected face-down output, the
exit junction gate sends the page to the inverter. The inverter inverts the page for face-down output.
If the user selected duplex mode, after the inverter inverts the page, the duplex junction gate directs the
page into the duplex unit, then the duplex unit feeds the page back to the machine for printing the second
side.
• When the duplex unit is removed, the trailing edge guide plate (6) drops to the horizontal position to
make it easier to remove.
