The pick roller picks and the feed roller feeds the paper to the separator roller or separator pad. The
feed roller feeds the paper to the transport roller. For MPF print jobs, the MPF pick roller picks and
feeds the paper to the transport roller.
The transport rollers feed the paper to the transfer roller. At the transfer roller, the photoconductor
transfers the developed image to the paper to create the printed image.
As the paper passes the fuser, heat and pressure are applied to permanently bond the toner to the
paper.
After printing, the paper exit roller ejects the paper to the output bin.

After the first side is printed, the paper stops at the output bin while still in the paper exit roller. The
paper is fed again into the duplex paper path to have the opposite side printed.
The paper travels along the duplex path until it enters again the transport roller. From there, the
paper continues its path until the print job is done.
