Duplexing reverse/feed operation
The duplexing unit reverses the feed/delivery rollers in the device to print on both sides. The media that
passed through the fuser unit reverses its feeding direction and is fed to the duplexing unit. The duplexing
unit feeds the media and performs horizontal registration to align the starting position of the main scan
for the second-side print. Then, the media is fed into the device engine unit again.
