MX-1800N  DUPLEX SECTION  G – 2
2. Operational descriptions
A. Duplex section
• Paper is transported from the fusing section and sent to the
transport roller 13 driven by the paper exit drive motor and to the
paper exit roller 1. 
At that time, paper passes under the ADU reverse gate guide.
• After the specified time from detection of paper lead edge by
POD1, the paper exit drive motor is rotated forward, and after the
specified time, it is rotated reversely.
• At that time, paper passes the right side of the ADU gate guide
by its own weight.
• The transport rollers 10 and 11 are driven by the ADU motor
lower, and paper is transported to the duplex paper feed position.
• Paper is stopped at the duplex paper feed position, and trans-
ported to the inside of the machine again.
