•
For duplex printing, the second page (rear side) is printed first.
•
To print on the second side, the duplex inverter unit (on the side of the machine)
inverts the paper from the fusing unit and feeds it to the duplex feed unit (inside
the machine).
• The duplex feed unit feeds the inverted paper back to the paper feed section.
•
When both sides have been printed, the duplex inverter unit feeds the paper out
to the finisher.
•
If the mailbox or standard exit tray (on top of the machine) was selected to
receive the duplex copies, the print will not enter the duplex unit after the second
side has been printed. The junction gate inside the machine directs it upwards to
the selected tray.
•
Duplex copies are not fed out to the external tray (on the left of the machine).
