clutch again. The feed roller moves the media farther into the product. The registration shutter corrects page skew and the media is transported to the fuser/delivery block. Fuser/delivery block The fuser/delivery block consists of 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 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 media movement, jams, and the top output-bin capacity. Pressure roller pressure release control The product releases the pressure roller except during a print operation to improve usability for jammed paper removal. The DC controller reverses the fuser motor (M299) to rotate the fuser pressure release cam. The pressure roller is pressurized or depressurized due to the shape of the cam. The DC controller reverses the fuser motor to control the pressure roller pressurize or depressurize state according to the signal sent from the fuser pressure release sensor (PS699).
