MPF Paper Feed
To start the paper feed, the printer controller sends a signal to turn on the MPF feed clutch; the paper
feed motor starts turning the Paper Feed Roller to feed the top sheet of paper in the MPF tray one by
one. Once the duplex exit/MPF detection lever senses the leading edge of the media at the duplex exit
roll, it engages the duplex re-feed clutch to transport the sheet of paper into the paper path.
