MX-M1100  ADU PAPER EXIT SECTION  O – 3

When duplex print is selected, paper printed on the first side is
switched back to feed to the duplex section to make duplex print.
Inverting / Duplexing Path

When duplex print is selected, the paper is passed under the face-
up / face-down select gate.
At the same time the duplex select gate is on, the paper is passed
to ADU paper guide.
Paper is reversed by ADU reverse motor.

The second paper completes switchback and is passed to the
reverse gate. 
The first paper is reversed from the reverse gate and passed to
copy operation of the back surface. 

The fourth paper is transported to the ADU and then the face-up /

dace-down select gate is turned OFF to discharge the first paper. 

The front surface of the fifth paper is copied after the second paper.
