Feeding paper from the MPF
To start the paper feed, the printer controller sends a signal to turn on the MPF feed clutch; the paper feed motor
starts turning 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 roller, it engages the duplex re-feed clutch to
transport the sheet of paper into the paper path.
