■ Duplexing Reverse Control
When the leading edge of paper reaches the duplexing vertical path sensor 4, the paper is
fed by the specified distance and the paper pauses where the trailing edge of paper is in the
duplexing reverse position.
After the paper pauses, the motor makes negative rotation if there is no paper on the wait
position at downstream (refer to Duplexing Wait Control for details) and the paper is fed to the
duplexing feed area.
