Figure 21. Paper pickup/feed and fuser/delivery block diagram

The fuser/delivery block consists of the various rollers, sensors, the fuser, and the output delivery assembly. The rollers transport the media through the fuser/delivery block paper path. The fuser applies heat and pressure to the media to permanently bond the toner image (which was transferred to the media from the photosensitive drum in the print cartridge) to the media. The output delivery assembly sends the printed media either to the rear output bin (if the rear output door is open) or to the top output bin (the default output delivery bin). Sensors along the paper path detect the movement of the media, jams if they occur, and when the top output bin is full.
