The media with the embedded toner image goes through the fuser assembly to permanently bond the toner
to the media. When it passes between the heat belt and pressure roll of the fuser assembly, the combination
of heat and pressure fuses the toner image to the media. The fuser exit roller feeds the media to the paper exit
roller and then to the output bin.

Duplex printing
After the first side of the media has been printed on and is partially fed out to the output bin, the duplex solenoid
activates. This causes the exit roller to reverse its rotation and feed the media, with its trailing edge first, back
into the redrive assembly and then to the duplex paper path. The duplex front and rear deliver rollers move the
media through the duplex paper path, the diverter, the first input roller, and back to the primary paper path. The
same process for printing on the first side of the media repeats, this time for the second side of the media.
