Multipurpose feeder (MPF)
The driving force from the main drive motor is transmitted through the MPF gearbox. When the MPF solenoid
activates, it allows the MPF sector gear linked to the MPF gearbox to rotate. The MPF pick roll shaft is connected
to the MPF sector gear.
The MPF can be accessed by opening the MPF tray on the front door. In an MPF paper feed, the MPF paper
present sensor detects the media. The instant the MPF pick roll shaft rotates, the cams on each end of the shaft
disengage the MPF tray. Each side of the tray is connected to the front access cover by springs. When
disengaged from the shaft, the springs pull the tray causing the media to come into contact with the MPF pick
roller. At the same time the pick roller rotates, pushing the media to the separator pad. The media does not
pass through the secondary input roller, but directly to the first input roller.

Situated along the first input roller, is the deskew shutter. It subjects the media to a deskewing force based on
the media width. The direction of the force is transverse to the feed direction. The leading edge of the media
then passes though the input sensor.
After the edge of the media is aligned, the first input roller feeds the media to the transfer roll for toner transfer.
At this point, the toner image is already on the photoconductor drum surface. As the media passes between
the photoconductor drum and transfer roll, the toner image is transferred to the media.
